a) Reasons why UV Irradiation generated using LPMVL is an effective primary disinfectant: Ultraviolet irradiation (UV) is a reliable, cost-effective technique that does not introduce any chemical substances to the water, making it a desirable disinfectant option.

This method employs UV lamps to radiate UV rays, typically in the 254-nm range, in a low-pressure mercury vapor lamp (LPMVL).UV disinfection inactivates a variety of bacteria, viruses, and protozoa, including those that cause Cryptosporidiosis and Giardia.

b) While UV disinfection is effective against most bacteria and viruses, it is not as effective against cysts, which are protozoan organisms with a thick outer shell that protects them from UV radiation. The cysts are not killed but become inactive  when conditions are favorable, they can become active again and continue to cause illnesses.

c) The main property of chlorine in water that makes it the best choice as a secondary chemical disinfectant: Chlorination is the most commonly used secondary disinfectant in drinking water treatment facilities. Chlorine has a number of beneficial characteristics, including being a strong oxidant that can quickly inactivate many pathogens, including bacteria, viruses, and cysts.

a) Calculation of Total flow rate To calculate the total flow rate through the pipe system, we use the following formula:$$Q=\frac {vA}{n} $$Where Q is the flow rate, v is the average velocity, A is the cross-sectional area of the pipe, and n is the Manning's coefficient of the material.

Here, the diameter of each pipe is 250 mm or 0.25 m. The area of a circle of radius 0.125 m is given by πr², which is 0.0491 m². The velocity of the flow is not given, so we need to calculate it. Since the pipes are all the same size and length, we can assume that the frictional loss in each pipe is equal, and we can calculate the total head loss as the sum of the head loss in each pipe.

To calculate the head loss in each pipe, we use the Darcy-We isbach equation:$$hf=\frac{fL}{D}\frac{v^2}{2g}$$Where hf is the head loss due to friction, f is the friction factor, L is the length of the pipe, D is the diameter of the pipe, v is the velocity of the flow, and g is the acceleration due to gravity (9.81 m/s²).

The friction factor depends on the Reynolds number, which is given by: $$Re=\frac{vD}{\nu}$$Where ν is the kinematic viscosity of the fluid, which is 1.004 × 10⁻⁶ m²/s for water at 20°C. Since the flow is turbulent, we use the Colebrook equation to calculate the friction factor:

We can solve this equation for f using the Newton-Raphson method. Since the elevation of the upstream reservoir is 95 m and the elevation of the downstream reservoir is 70 m, the total head loss due to elevation is 25 m. The elevation head loss is given by:

When heating a fixed mass of an ideal gas from 50 to 80 degrees Celsius at constant pressure, the energy required will be greater for the sample at 3 atm compared to 1 atm.

In the second question, when heating air at constant pressure from 250 to 350 K and from 450 to 550 K, both cases will require the same amount of energy as the specific heat of an ideal gas does not vary with temperature.

In the first scenario, when heating the gas from 50 to 80 degrees Celsius at constant pressure, the energy required is directly proportional to the change in temperature. Since the temperature change is the same for both cases (30 degrees Celsius), the energy required will be greater for the sample at 3 atm because it experiences a larger pressure, resulting in a higher energy requirement.

In the second scenario, when heating air at constant pressure, the energy required is determined by the temperature change, not the specific temperatures themselves. The specific heat of an ideal gas does not vary with temperature, meaning the energy required will be the same for both cases. The difference in initial and final temperatures is the same (100 K) for both samples, resulting in an equal energy requirement.

Therefore, in both cases, the energy required is greater for the sample at 3 atm in the first scenario, and the energy requirements are the same for both samples in the second scenario due to the properties of ideal gases and constant pressure conditions.

The depreciation charge for the third year and Book value of asset after third year of the depreciation are $3840 and $5760 respectively.

Given data:

To calculate the depreciation charge for a specific year using the Modified Accelerated Cost Recovery System (MACRS), we need to use the MACRS depreciation formula for the given year. The formula for the depreciation charge for a specific year is:

Depreciation Charge = (Cost Basis × Depreciation Percentage for the Year)

For a 5-year MACRS schedule, the depreciation percentages are as follows:

Year 1: 20.00%

Year 2: 32.00%

Year 3: 19.20%

Year 4: 11.52%

Year 5: 11.52%

Given:

Cost Basis = $20,000

Year = 3 (third year)

Depreciation Charge for the third year = ($20,000 × 19.20%) = $3,840

Now, to calculate the book value of the asset after the third year, we need to subtract the accumulated depreciation from the initial cost basis:

Accumulated Depreciation after the third year = Depreciation Charge for Year 1 + Depreciation Charge for Year 2 + Depreciation Charge for Year 3

Accumulated Depreciation after the third year = ($20,000 × 20%) + ($20,000 × 32%) + ($20,000 × 19.20%)

On simplifying the equation:

= $4,000 + $6,400 + $3,840

= $14,240

Book Value after the third year = Initial Cost Basis - Accumulated Depreciation after the third year

Book Value after the third year = $20,000 - $14,240

= $5,760

Hence, the book value after the third year is $5,760.

The work developed by the turbine per unit of mass flowing is approximately 175 J/kg, and the nitrogen temperature at the turbine outlet is approximately 155.55 °C.

(a) The calculation of work developed by the turbine per unit of mass flowing can be determined using the given formula. The isentropic turbine efficiency (ηis) is calculated as the ratio of the enthalpy difference between the inlet and the isentropic outlet to the enthalpy difference between the inlet and the actual outlet.

Δh = (h1 - h2s)

ηis = (h1 - h2s)/(h1 - h2)

To calculate the turbine work output (W), we need to determine the value of h2 using steam tables at 2 bar. Then, substituting the known values into the equation, we obtain:

W/m = (h1 - h2s) - (h1 - 13 bar, 300 °C) × 0.8

W/m = (1 - 0.7942) × (3433 - 2584) J/kg

W/m = 0.206 × 849 J/kg ≈ 175 J/kg

(b) To calculate the nitrogen temperature at the turbine outlet, we can use the ideal gas law equation PVn = constant. Given P1, V1, P2, and V2, we can determine the temperature T2 at the outlet.

P1V1n = P2V2n

V1 = m/n = (22.414/28) = 0.8005 m³/kg at 13 bar, 300 °C

P2 = 2 bar and V2 = 0.8005 m³/kg at the outlet

T2 = (P2V2n / R) = [(2 × 105 × 0.8005) / (29)] K ≈ 428.55 K ≈ 155.55 °C

Therefore, the nitrogen temperature at the turbine outlet is approximately 155.55 °C.

CSTR and PFR are two common types of chemical reactors. CSTR is suitable for liquid-phase reactions with long reaction times, while PFR is ideal for gas-phase reactions with short reaction times and high heat generation. CSTR is commonly used in wastewater treatment and large-scale processes, while PFR finds application in fast chemical reactions and industrial processes.

Plug Flow Reactor (PFR) and Continuously Stirred Tank Reactor (CSTR) are two common types of chemical reactors. The reactor's characteristics determine the type of reaction that can occur within it.

Continuously Stirred Tank Reactor (CSTR)

In a Continuously Stirred Tank Reactor (CSTR), the reactants are continuously fed into the tank, mixed, and then allowed to exit the reactor. The reactants are thoroughly combined, and the reactor contents are constantly homogenized. This means that the concentration of the reactants is uniform throughout the reactor. It is used to handle systems that have a long reaction time and a high degree of uniformity. This reactor type is ideal for liquid-phase reactions.

Plug Flow Reactor (PFR)

In a Plug Flow Reactor (PFR), the reactants are fed into a long, tubular reactor. The reactants only flow in one direction in this reactor, hence the name. As a result, there is no axial mixing in this reactor. The reactants are continuously fed into the reactor's front end and then allowed to exit the reactor at the back end. This reactor is ideal for gas-phase reactions where short reaction times are required. In comparison to CSTRs, PFRs have a high degree of concentration change across the reactor. It is important to note that PFRs can only be used for exothermic reactions that generate a lot of heat, since they are inherently isothermal.

Circumstances for each reactor type:

CSTRs are often used in situations where the process has a long residence time, which means that the reactants must remain in the reactor for an extended period of time to achieve the desired reaction. CSTRs are frequently used in wastewater treatment plants, which can run continuously and are particularly well-suited for anaerobic digestion processes. CSTRs are also well-suited for large-scale processes, such as the production of antibiotics and biological drugs.

PFRs are frequently used for fast chemical reactions, such as the production of polymers, that require a small residence time. Furthermore, PFRs can only be used for exothermic reactions that generate a lot of heat, since they are inherently isothermal. As a result, they are often used in industrial chemical processes, such as the synthesis of chemicals and the production of petroleum products. PFRs are most commonly used in gas-phase reactions.

Capitalized cost is the total present value of an asset's cost, which includes its acquisition price as well as all future expenses and/or revenue over its lifetime. In this question, we are given that a machine costs P300,000 new and must be replaced every 15 years, with an annual maintenance cost of P5,000.

The salvage value is P50,000, and the money is worth 5%. We must calculate the capitalized cost. The formula to find the capitalized cost is:

Capitalized cost = First cost + Present worth of the annual maintenance cost + Perpetuity of the depreciation cost - Salvage value
First cost = P300,000
Present worth of the annual maintenance cost = A(P/F, 5%, 15) x 5,000
= 4.0468 x 5,000
= P20,234

Perpetuity of the depreciation cost = D(P/A, 5%, 15) x (P300,000 - P50,000)
= 9.449 x 250,000
= P2,362,227.34

Salvage value = P50,000
Capitalized cost = P300,000 + P20,234 + P2,362,227.34 - P50,000
= P2,632,461.34

To estimate the membrane area required for the artificial kidney using a cellophane membrane, we need to calculate the effective diffusivity of urea through the membrane and use it in conjunction with the concentration difference across the membrane. Without the mass flow rate, it is not possible to directly calculate the membrane area required for the artificial kidney

The parameters for the cellophane membrane are provided, as well as the diffusivity of urea in a dilute aqueous solution.

The effective diffusivity of urea through the cellophane membrane can be calculated using the equation:

D_eff = (D * porosity) / tortuosity,

where D is the diffusivity of urea in dilute aqueous solution. Substituting the given values, we have:

D_eff = (1.38 × 10^–5 cm^2/s * 0.45) / 5.0.

Next, we can estimate the mass flow rate of urea through the membrane using Fick's first law of diffusion:

J = -D_eff * (C2 - C1) / Δx,

where J is the mass flow rate, C2 and C1 are the concentrations of urea on each side of the membrane, and Δx is the thickness of the membrane. The mass flow rate can be determined by multiplying J by the area of the membrane. However, the concentration difference and the thickness are given, but the mass flow rate is not provided in the question.

The deflection at any point on a fixed beam that is subjected to a uniformly distributed load over its span can be obtained by the moment area method. The moment area method is a graphical method that involves the use of bending moment diagrams to determine the deflection of a beam.

The method is based on the principle that the deflection of a beam is proportional to the area of its bending moment diagram. In other words, if the bending moment diagram of a beam is known, the deflection of the beam can be determined by finding the area of the bending moment diagram and multiplying it by a constant factor.

This constant factor is known as the slope or curvature factor and depends on the beam's boundary conditions and load distribution. The formula for the deflection of a beam using the moment area method is given by: δ(x) = (1/EI)∫M(x)L(x)dx Where δ(x) is the deflection of the beam at any point x, E is the modulus of elasticity of the beam's material,

I is the second moment of area of the beam's cross-section, M(x) is the bending moment at any point x, and L(x) is the length of the beam to the left of point x. The conjugate beam method is a powerful tool used in structural analysis to determine the deflection and slope of a beam.

It involves the transformation of a real beam into an imaginary beam called a conjugate beam, which is easier to analyze because it has the same boundary conditions as the real beam but is subjected to an imaginary load that is equal and opposite to the real load. The deflection and slope of the real beam are then obtained by applying the same formulas used for the conjugate beam.

The moment at the left support is -22.5 kN-m.

The moment at the right support is 22.5 kN-m.

The maximum deflection of the beam is approximately 0.050 mm.

Ml + (30 kN * (4.5 m - 1.5 m)) - (30 kN * (4.5 m/2)) = 0

Ml + (30 kN * 3 m) - (30 kN * 2.25 m) = 0

Ml = (30 kN * 2.25 m) - (30 kN * 3 m)

Ml = -22.5 kN-m

The moment at the left support is -22.5 kN-m.

Mr + (30 kN * (4.5 m/2)) - (30 kN * (4.5 m - 1.5 m)) = 0

Mr + (30 kN * 2.25 m) - (30 kN * 3 m) = 0

Mr = (30 kN * 3 m) - (30 kN * 2.25 m)

Mr = 22.5 kN-m

Therefore, the moment at the right support is 22.5 kN-m.

= (1 m * (4.5 m)³) / 12

I = 3.375 m⁴

Now we can calculate the deflection:

δ =[tex](5 * 30 kN * (4.5 m)^4) / (384 * 160,000 kN/m^2 * 3.375 m^4)[/tex]

δ ≈ 0.050 mm

Therefore, the maximum deflection of the beam is approximately 0.050 mm.

The critical precrack size that would reduce the failure strength (σf) to below the yield strength (σy) is 0.25 mm.

Given data, Stiffness = E = 200 GPa

Strength = σf = 400 MPa

Toughness = KIC = 80 MP[tex]a.m^{1/2}[/tex]

Critical pre-crack size is to be calculated, which reduces the failure strength (σf) to below the yield strength (σy)We know that when a crack length of a component is greater than the critical crack length, the component will fail when subjected to a certain stress level. So, the fracture strength of the material with pre-crack can be calculated as:

σf = Y * [KIC / [tex]a^{1/2}[/tex]]        ---- (1) where, a is the crack siz eY = 1 (As given)

Using Young's modulus, E = σf / εf and σy = σf/2, we get: εf = σf / Eσy = σf / 2        ---- (2)

Now, we will substitute Equation (2) in Equation (1)

σy = Y * [KIC / [tex]a^{1/2}[/tex]]

σy / Y = KIC / [tex]a^{1/2}[/tex])

σy^2 / [tex]Y^{2}[/tex] = KIC / aσ[tex]y^{2}[/tex] * a = KIC * [tex]Y^{2}[/tex]a = KIC * [tex]Y^{2}[/tex]/ σ[tex]y^{2}[/tex]a = (80 * [tex]10^{2}[/tex] * [tex]1^{2}[/tex]) / (400 * [tex]10^{6}[/tex])^2a = 0.00000025 m = 0.25 mm

Therefore, the critical precrack size that would reduce the failure strength (σf) to below the yield strength (σy) is 0.25 mm.

Sustainability is a vital aspect in the building and construction industry. The key focus areas for the industry in the future include sustainability of the environment, economy, and society. While most countries have similar focus areas, their approach and actions towards sustainability may differ for various reasons.


Reasons for Differences in Sustainability Requirements:-

1. Climate
The climate in the US varies depending on the region. For instance, the southern and western regions experience more extreme temperatures compared to the northern regions.
2. Population Density
The US has a lower population density compared to the Netherlands, which means that they have more land and resources available. The Netherlands, being more densely populated, requires more efficient use of land and resources.

3. Political Culture
The US has a more individualistic political culture that promotes economic growth. This has led to a slower adoption of sustainability practices, while the Netherlands has a more collectivist political culture that promotes social equality and sustainability.

Their approach to handling these issues is different due to various reasons such as climate, geography, and political culture. By examining the sustainability elements and reasons for differences in sustainability requirements, it is evident that the US and the Netherlands have unique approaches to handling sustainability issues.

Rock storage pile is a type of heap of rocks that is designed and constructed for an industrial purpose or mining operations. The rock storage pile is lined with reinforced GCL (Geosynthetic Clay Liner) overlaid by a 1.5 mm thick HDPE geomembrane.

A heavy nonwoven geotextile is then placed on top of the geomembrane. K = 10-2 cm/s because the rock is porous, and it is used as the main LCS stone, so no extra leachate collection stone is being mounted. The design storm is 0.8 cm rain/day, and the pipe-to-pipe lateral spacing is 60 m.

[tex]θ = tan^-1[(i*L)/(H + L/2)][/tex]
Where θ = the base slope, i = the rainfall intensity, L = the pipe-to-pipe distance, and H = the maximum allowable head.
Plugging in the values,

[tex]θ = tan^-1[(0.008 * 60)/(0.25 + 60/2)][/tex]
[tex]θ = tan^-1[(0.48)/(30.25)][/tex]
[tex]θ = tan^-1[0.0158][/tex]
[tex]θ = 0.9°[/tex]
Thus, a base slope of 0.9° or 1.57% is required to keep the head below 25 cm.
Therefore, the rock storage pile is a reasonable material to replace the LCS stone because it provides the required porosity for better leachate discharge.
