Answers

Answer 1

The karstic limestone formation is a unique geological formation, which poses a significant challenge for the construction of highways in Ampang Hilir, Kuala Lumpur. It is necessary to investigate the site and collect data to provide information for design and construction and also for environmental assessment.

the proposed cost-effective method of ground exploration should include a detailed geological survey of the site. This survey should include the identification of the type and thickness of the limestone rock and the depth of the bedrock .The suitable in-situ testing should include a series of tests such as the Standard Penetration Test (SPT), which is a quick and cost-effective method of determining the strength of the soil and the depth of the bedrock. Another suitable test is the Cone Penetration Test (CPT), which is more accurate and provides data on the strength and stiffness of the soil and rock.

These tests can help determine the properties of the limestone formation and the strength of the soil, which is essential for designing a suitable foundation for the highway. The information gathered from the site investigation will provide the necessary data for the design of a suitable foundation for the highway. The design should take into account the strength of the limestone formation and the depth of the bedrock. The foundation design should also consider the potential for sinkholes and other ground subsidence issues associated with karstic limestone formations.

a-A rectangular channel, B = 3.0 m and n = 0.015 and length of 1000 meter, connects two reservoir. The channel slope is 0.02. At the intake the bed of the channel is at an elevation of 100.00 m. If the upstream reservoir water surface changes between 102.00 m to 105.00 m, calculate the depth-discharge curve in the channel. The entrance losses can be neglected. b- if the channel slope changes to 0.002 and downstream water surface is constant and equal to 102.00 m how much is the maximum discharge between two reservoirs by changes water surface level in upstream reservoir while downstream water surface is constant and equal to 102.00 m?

Answers

a)To find the depth-discharge curve in the channel, we need to use Manning's equation. Manning's equation for flow through a channel is given by; $$ [tex]Q=\frac {1}{n}A R^{2/3} S^{1/2}$$.[/tex]

Where Q is discharge, A is the cross-sectional area of flow, R is the hydraulic radius, S is the slope, and n is the Manning roughness coefficient.  

Thus the depth-discharge curve in the channel is the same as that between the two reservoirs. The discharge can be calculated by substituting the respective values into the Manning's equation;

$$[tex]Q=\ frac {1}{n}A R^{2/3} S^{1/2}$$[/tex]  Here, the slope S = 0.02, and n = 0.015Thus, discharge between the two reservoirs is Given, width of channel,

Thus, the depth-discharge curve for the downstream water surface elevation of 102 m will be the same as the depth-discharge curve calculated earlier.

Calculate the total live load on a dairy barn floor for calves. The Calves apply a load of 50 PSF. The floor is 15' by 49' and has a density of 150 PSF. The walls and roof apply a load of 200 PSF. What is the total load?

Answers

Live load is a term used to describe the weight that is temporarily added to a structure, such as a building, and then removed again. It is a measure of the weight that is placed on a structure due to its intended use. In this case, we are trying to calculate the total live load on a dairy barn floor for calves. Here are the steps to find the total load:

Step 1: Calculate the load applied by the calves. Calves apply a load of 50 PSF. The floor is 15' by 49'.Area of the floor = length × breadth = 15 × 49 = 735 sq. ftLoad applied by calves = load per sq. ft × area of the floor= 50 × 735= 36750 pounds

Step 2: Calculate the density of the floor. The density of the floor is given as 150 PSF. This means that every square foot of the floor weighs 150 pounds. Density of the floor = 150 pounds per sq. ft.

Step 3: Calculate the weight of the floor. Weight of the floor = area of the floor × density of the floor= 735 × 150= 110250 pounds.

Step 4: Calculate the load applied by the walls and roof. The walls and roof apply a load of 200 PSF.Load applied by the walls and roof = 200 pounds per sq. ft.

Step 5: Calculate the total load. Total load = weight of the floor + load applied by the walls and roof+ load applied by the calves= 110250 + (200 × 735) + 36750= 246750 pounds Therefore, the total live load on a dairy barn floor for calves is 246750 pounds.

THe coefficient associated with natural convection is h = 10W/m^2 K. The surface emissivity is 0.8 what is the rate of heat loss from the steam line? what is the outside surface temperature of the asbestos paper?

Answers

The thermal conductivity of the Stainless steel AISI 304 steam pipe at around 600K is 14.4 W/m K. The rate of heat loss from the steam line is 48.3 W, and the outside surface temperature of the asbestos paper insulation is 77.8°C.

(3-1) The thermal conductivity of Stainless steel AISI 304 at around 600K is given by:

K = qdA(T2 - T1)L

where:

q = heat flow rate = 0.005 W/d^2 = 0.005 W/(0.008m^2) = 0.625 W/m^2

A = cross-sectional area = πd^2/4 = π(0.08)^2/4 = 0.00502 m^2

d = outside diameter of the pipe = 0.08 m

L = length of the pipe = 30 m

T1 = outside temperature of the pipe = 30°C = 303 K

T2 = temperature inside the pipe = 150°C = 423 K

Substituting the values in the above equation, we get:

K = 0.625 × 0.00502/ (423 - 303) × 30

 = 14.4 W/m K

Therefore, the thermal conductivity of the steam pipe, Stainless steel AISI 304 at around 600K is 14.4 W/m K.

(3-2) Given that:

The coefficient associated with natural convection is h = 20 W/m² K

The surface emissivity is 0.8

The length of the uninsulated steam pipe is L = 30m

The outside diameter of the uninsulated steam pipe is d0 = 80mm = 0.08m

Pressurized steam maintains a pipe surface temperature of 150°C

The temperature of air around the steam pipe is Ta = 30°C = 303K

The rate of heat loss from the steam line is given by:

Q = 2πLh(Ts − Ta)d0(1 − ε)

where:

Ts = surface temperature of the steam pipe

ε = surface emissivity of the steam pipe

Substituting the values, we get:

Q = 2π × 30 × 20 × (150 − 30) × 0.08 × (1 − 0.8)

 = 48.3 W

The outside surface temperature of the pipe can be obtained from the equation:

Q = (Ts - Ta)/[(1/h) + (log r2/r1)/(2πk)]

where:

r2 = outside radius of insulation + outside radius of the steam pipe = 0.01m + 0.04m = 0.05m

r1 = outside radius of the steam pipe = 0.04m

Substituting the values, we get:

48.3 = (Ts - 303)/[(1/20) + (log 0.05/0.04)/(2π × 14.4)]

Ts = 74°C

(3-3) Given that:

The coefficient associated with natural convection is h = 10 W/m² K

The surface emissivity is 0.8

The length of the uninsulated steam pipe is L = 30m

The outside diameter of the uninsulated steam pipe is d0 = 80mm = 0.08m

Pressurized steam maintains a pipe surface temperature of 150°C

The temperature of air around the steam pipe is Ta = 30°C = 303K

The thickness of the insulation layer is L1 = 10mm = 0.01m

The coefficient associated with natural convection is h = 10 W/m² K

The rate of heat loss from the steam line is given by:

Q = 2πL1k1(Ts1 − Ts2)/(ln (r2/r1) )

+ 2πL2h(Ts2 − Ta)d0(1 − ε)

where:

Ts1 = temperature of the outer surface of the insulation layer

k1 = thermal conductivity of the insulation material

L2 = length of the insulated steam pipe = L = 30m

Ts2 = temperature of the outer surface of the steam pipe

ε = surface emissivity of the steam pipe

Substituting the values, we get:

48.3 = 2π × 0.01 × k1 × (Ts1 − 150)/(ln (0.04/0.05)) + 2π × 30 × 10 × (Ts2 − 303) × 0.08 × (1 − 0.8)

where k1 = 0.16 W/m K (assumed value of thermal conductivity of asbestos paper)

Solving the above equation, we get:

Ts1 = 77.8°C

Ts2 = 89.3°C

Therefore, the rate of heat loss from the steam line is 48.3 W and the outside surface temperature of the asbestos paper is 77.8°C.

Answers

The Rayleigh-Ritz Method is a powerful tool for calculating the shape of the deflected curve for the beam. This method uses a series of trial functions to approximate the shape of the beam's deflection. Once the shape of the deflected curve has been approximated, the shear and moment diagrams can be determined.

Let's see how the Rayleigh-Ritz Method can be applied to the two functions given in the question. a.) u(x)=-c0 sin (πx/L)We can use the following trial function: u(x) = a0 + a1x + a2x² + a3x³ + a4x⁴Using this trial function, we can find the coefficients a0, a1, a2, a3, and a4 that will approximate the deflection function. The coefficients can be found by minimizing the following energy functional:

E = ∫₀^L [M(x)u'(x)² - V(x)u(x)²] dx where M(x) is the bending moment and V(x) is the shear force. We will assume that M(x) = EIu''(x) and V(x) = -EIu'''(x). The Rayleigh-Ritz Method requires us to choose trial functions that satisfy the boundary conditions. For this problem, we have u(0) = u(L) = 0. Plugging the trial function into the boundary conditions, we get:

a0 = 0 and a0 + a1L + a2L² + a3L³ + a4L⁴ = 0Using these boundary conditions, we can find the coefficients for the trial function. The deflection function can be approximated as follows: u(x) = -c0 [2(1-4/pi²) sin (πx/L) + 2/3 sin (3πx/L) - 4/pi² sin (5πx/L) + ...]Using this approximated deflection, we can calculate the shear and moment diagrams for the beam.

Content Mtsemus D. Why do we take the internal pressure in our casing to be zero when calculating collapse loads ?

Answers

When calculating collapse loads, the internal pressure in a casing is assumed to be zero. In this regard, this question seeks to answer the reason why the internal pressure is set to zero when determining the collapse loads.

The internal pressure in the casing is the pressure that is exerted inside the casing. When the pressure inside the casing is high, the casing wall will experience tension. On the other hand, if the internal pressure is low, the casing wall will experience compressive stress. The higher the internal pressure in the casing, the greater the tension that the casing wall will experience. This, in turn, makes the casing more susceptible to collapse. It is for this reason that when calculating collapse loads, the internal pressure in the casing is assumed to be zero. This assumption ensures that the calculations are carried out under the worst-case scenario. In conclusion, the internal pressure in a casing is assumed to be zero when calculating collapse loads because the higher the internal pressure, the greater the tension that the casing wall will experience. This makes the casing more susceptible to collapse.

Answers

The goal of Boeing, Inc is to determine whether an existing machine can mill an engine part that has a design specification of 5.0mm +- 0.10 mm. The process has a standard deviation of σ = 0.02 mm.

Given that the standard deviation of the process is σ = 0.02 mm. Now, we need to determine if the existing machine can produce a part that meets the design specification using the given standard deviation (σ).The tolerance limit (T.L) can be calculated as;

T.L = (Upper Limit – Lower Limit) / 2 where;

Upper Limit = 5.0 + 0.10 = 5.10 mm

Lower Limit = 5.0 – 0.10 = 4.90 mm

T.L = (5.10 – 4.90) / 2 = 0.10 / 2 = 0.05 mm

The value of T.L = 0.05 mm

The process standard deviation (σ) = 0.02 mm

Using the formula;

P = 0.6827, approximately 68.27% of the parts produced by the existing machine fall within the tolerance limit (5.0 ± 0.10)

With a process standard deviation of σ = 0.02 mm and a tolerance limit of 0.05 mm, approximately 68.27% of the parts produced by the existing machine fall within the tolerance limit (5.0 ± 0.10).

Two gray bodies: Body 1 at 200oC and Body 2 at 100oC with emissivities of 0.6 and 0.8 respectively.

Required: The net heat transfer rate by radiation from Body 1 to Body 2 per m2, if: Bodies 1 and 2 are parallel disks each with 4 cm radius and 5 cm apart.

Answers

The net heat transfer rate by radiation from Body 1 to Body 2 per square meter is approximately 10.35 W/m^2.

The problem concerns the radiation heat transfer between two parallel disks. The disks have radii of 4 cm and emissivities of 0.6 and 0.8. They are maintained at temperatures of 200°C and 100°C respectively, with a distance of 5 cm between them. The objective is to determine the net heat transfer rate per square meter from Body 1 to Body 2, assuming no convective heat transfer occurs between the disks.

To calculate the heat transfer rate by radiation, the Stefan-Boltzmann law is applied:

q'' = σA1A2 (T1^4 - T2^4) / πD^2

Where:

q'' is the heat transfer rate by radiation

σ is the Stefan-Boltzmann constant (5.67 x 10^-8 W/m^2-K^4)

A1 and A2 are the areas of the two disks

T1 and T2 are the temperatures of the two disks

D is the distance between the two disks

From the equation, it is evident that the heat transfer rate by radiation is directly proportional to the area of the disks and the temperature difference between them, while inversely proportional to the square of the distance between them.

Calculating the area of each disk, A, we find A = πr^2 = 3.14 x 4^2 / 10000 = 0.000502 m^2.

Substituting the given values into the Stefan-Boltzmann law, we obtain:

q'' = 5.67 x 10^-8 x 0.000502 x 0.000502 x (473.15^4 - 373.15^4) / (π x 0.05^2)

≈ 10.35 W/m^2

Therefore, the net heat transfer rate by radiation from Body 1 to Body 2 per square meter is approximately 10.35 W/m^2.

Answers

Kutter and Ganguillet's formula is used to calculate the discharge of a pipe, and the formula is given below :$v =\frac{1}{n} R^{2/3} S^{1/2}$Where:v = velocity in m/sR = hydraulic radius in meter (A/P)S = slope of the energy line in m/mn = coefficient of roughness.

The formula for hydraulic radius is as follows:$R =\frac{A}{P} $where A is the cross-sectional area of the pipe and P is the wetted perimeter. By taking the velocity, hydraulic radius, and cross-sectional area of the pipe, we can determine the discharge of the pipe.

For a 3.0 m diameter pipe, if the depth of flow is 0.75 m, find the discharge by using Kutter and Ganguillet's equation.   The hydraulic radius can be calculated as follows:

Given that, Diameter = 3mRadius, r = Diameter/2 = 3/2 = 1.5mDepth of flow, y = 0.75 m   Area, A = πr²=π(1.5)²=7.069m²   Now, Wetted perimeter, P = 2πr$=2π×1.5=9.4248m$The slope of the energy line can be determined using the head loss formula, which is given as follows: Head loss per km length of pipe,

Answers

The statement "The critical stress rapidly decreases as the slenderness ratio increases" is false about long columns.

What are long columns?

A long column is a structural element that experiences compressive forces. It possesses a slenderness ratio exceeding 12, which represents the relationship between its length and its narrowest lateral dimension.

The pivotal stress denotes the maximum load that a column can sustain before succumbing to buckling. The slenderness ratio signifies the proportion between the column's length and its most diminutive cross-sectional dimension.

As the slenderness ratio amplifies, the critical stress diminishes. This phenomenon arises due to the heightened susceptibility of longer columns to buckle when subjected to external loads.

2). Derive the model energy equation (T), for a tank. Use: energy balance, energy generated by a heater and heat transfer to the outside.

Answers

The model energy equation for a tank is given by Cp * dT/dt = (Q_in - Q_out) / (dm/dt * de/dm), considering energy balance, heater input, and heat transfer to the outside.

To derive the model energy equation for a tank, we can use the principle of energy balance. The energy balance equation for the tank can be written as follows:

Rate of energy accumulation inside the tank = Energy input - Energy output

The rate of energy accumulation inside the tank can be expressed as the product of the mass of the fluid inside the tank and the rate of change of its internal energy with respect to time (dm/dt * de/dm * de/dt).

The energy input to the tank comes from the heater, which generates heat. Let's denote the rate of heat generated by the heater as Q_in.

The energy output from the tank is the heat transfer to the outside. The rate of heat transfer to the outside is given by Q_out, which is related to the heat transfer coefficient (h), the surface area of the tank (A), and the temperature difference between the tank and the surroundings (T - T_surroundings).

Therefore, the energy balance equation for the tank can be written as:

dm/dt * de/dm * de/dt = Q_in - Q_out

Next, let's express the rate of change of internal energy (de/dt) in terms of temperature (T) using the specific heat capacity (Cp) of the fluid inside the tank. The rate of change of internal energy can be written as:

de/dt = Cp * dm/dt * dT/dt

Substituting this into the energy balance equation, we get:

dm/dt * de/dm * Cp * dm/dt * dT/dt = Q_in - Q_out

Simplifying the equation, we have:

Cp * dm/dt * dT/dt = (Q_in - Q_out) / (dm/dt * de/dm)

Finally, rearranging the equation, we obtain the model energy equation for the tank:

Cp * dT/dt = (Q_in - Q_out) / (dm/dt * de/dm)

This equation represents the rate of change of temperature inside the tank (dT/dt) as a result of the energy input from the heater (Q_in) and the energy output through heat transfer to the outside (Q_out). The specific heat capacity (Cp) of the fluid and the rate of change of mass (dm/dt) and internal energy (de/dm) are also considered in the equation.

Explain the mechanism of SAP concretes. For shotcrete applications, which type of fibers would be recommended (steel or polymer). Explain why, in detail. Fibers are mainly active in which stage? Pre-crack or post-crack? What is the reason, explain in detail.

Answers

SAP (Super Absorbent Polymer) concrete is a new type of concrete that is reinforced by the addition of super absorbent polymer. The concrete is created by blending an absorbent polymer with Portland cement, sand, and water, which is then cured in a conventional manner.

SAP concrete's mechanisms are based on the swelling characteristics of the super absorbent polymer. The fibers recommended for shotcrete applications are polymer fibers, not steel fibers. Polymer fibers are recommended because they are less prone to corrosion than steel fibers. polymer fibers are less expensive than steel fibers and they can be easily added to the shotcrete mix.

The polymer fibers are also more effective in resisting plastic shrinkage than steel fibers. Since steel fibers are prone to corrosion, they are not recommended for shotcrete applications. This can lead to concrete damage and reduce its lifespan.

Fibers are mainly active in the post-crack stage rather than the pre-crack stage. This is due to the fact that fibers in concrete do not prevent cracks from forming; instead, they work to hold the concrete together after it has already started to crack. This ensures that the concrete remains stable and durable, even after experiencing some damage due to cracking.

A pad footing is a type of shallow foundation used to spread a concentrated load, such as that of a column. It is typically a square or rectangular slab of reinforced concrete that is used to transfer the load from a column or a wall to the underlying soil.

In this question, we are required to determine the size of a square pad footing to resist a characteristic axial load of 1000 kN and 350 kN d imposed loads from a 400 mm square column, given that the safe bearing pressure b) dead soil is 200 kN/m2 and fou = 30 N/mm, and fy = 460 N/mm2. The weight of the footing is also given to be 150 kN.

Step 1:    Determine the total load The total load on the footing can be calculated as follows: Total load = Characteristic axial load + Imposed loads + Self-weight= 1000 + 350 + 150= 1500 kN

Step 2: Determine the required area The required area of the footing can be determined by dividing the total load by the safe bearing pressure: Required area = Total load / Safe bearing pressure= 1500 / 200= 7.5 m2 Since the footing is square, the length and breadth of the footing will be equal. Hence, the side of the footing can be calculated as follows:

Answers

The recovery of certain capital expenditures that are not ordinarily deductible, in a manner that is similar to straight-line depreciation is defined in the US income tax code as amortization. Amortization refers to the practice of spreading an intangible asset's cost over the course of its useful life, much like depreciation and depletion.

This amortization process is used to reduce the asset's value in the balance sheet over time. Because it isn't considered a tangible asset, it cannot be depreciated.The IRS (Internal Revenue Service) allows a company to amortize or gradually depreciate intangible assets over their useful life. The amortization period can range from several years to several decades, depending on the asset's type and life span.

The cost basis is used in accounting and taxation to determine the starting point for determining gains and losses on investments and property sales. It is the total expense paid to acquire a specific asset, including any additional costs incurred in the acquisition, such as taxes, shipping, and installation expenses.

Depreciation allowances are deductions that businesses may claim for the loss of an asset's value over time. As a result, depreciation allowances are tax benefits that provide a reduction in taxable income, resulting in lower taxes.

The equivalent modulus of elasticity is given by:[tex]E = (Ast × Es + Ac × Ec)/(Ast + Ac[/tex])where, Ast = Area of steel, and Ac = Area of concrete.For circular columns, the area of steel,

Ast is given as:π/4 × (d² - d₁²)where, d₁ = Diameter of the longitudinal barsAst =[tex]π/4 × (d² - d₁²) = π/4 × (700² - 20²) = 38013.98 mm²[/tex]Let us assume the side cover as 50 mm, then, the area of concrete is:[tex]Ac = π/4 (d₁ - 2 × 50)² = π/4 × (20 - 2 × 50)² = 385298.73 mm²[/tex]

Now we can calculate E as:[tex]E = (Ast × Es + Ac × Ec)/(Ast + Ac) = (38013.98 × 420 + 385298.73 × 42285)/(38013.98 + 385298.73) = 25508.85 MPa[/tex]

Now substituting the values in the formula of critical axial load,

When streamlines are curved pressure increases inward towards the center of curvature of the streamlines O True O False
Flow is steady and non-uniform when it flows at varying rates through a duct of non-uniform cross-section O True O False

Answers

When streamlines are curved, the pressure increases inward towards the center of curvature of the streamlines. This statement is true.The concept of streamlines comes into play in fluid dynamics, which is the study of fluids' behavior when they are in motion. Streamlines are defined as the imaginary curves that follow the flow direction of a fluid.

The velocity of the fluid is tangent to the streamline, and it does not intersect the streamline. The term ‘streamline’ refers to a line in a fluid that a small particle follows as it travels along the path of the fluid. This can be seen in the way that smoke rises in the air, the way water flows through a river or over rocks, or the way air moves over a plane’s wing.

In a curved streamline, the fluid particles move in the form of a vortex, and the pressure at the center of the vortex decreases. Thus, the pressure outside the center increases, which leads to the inward pressure force towards the center of curvature of the streamlines.

Flow is steady and non-uniform when it flows at varying rates through a duct of non-uniform cross-section. This statement is false. A fluid is considered to have uniform flow if the flow parameters such as the velocity, density, and temperature remain constant over the entire flow area.
