A pipe is carrying water under steady flow conditions. At end point 1, the pipe diameter is 1.2 m, and the velocity is (48+30) mm/h. called point 2, the pipe diameter is 1.1 m.
We need to calculate the velocity in m/s at this end
[tex]Q = A1V1 = A2V2[/tex],where Q is the flow rate, A1 and A2 are the cross-sectional areas of the pipe at point 1 and point 2, respectively, and V1 and V2 are the velocities at point 1 and point 2,
Firstly, we will calculate the cross-sectional area of the pipe at point 1: Area at point 1 = [tex]π(1.2/2)²= 1.131 m²[/tex]
Now, we can calculate the flow rate at point 1:[tex]Q = A1V1(48+30) × 10⁻³ = 1.131 × V1V1 = (78/1.131) m/s = 68.89 m/s[/tex](approx)Next, we can calculate the cross-sectional area of the pipe at point 2:Area at point 2 = [tex]π(1.1/2)²= 0.95 m²[/tex]
Finally, we can use the continuity equation to find the velocity at point 2:[tex]Q = A1V1 = A2V2V2 = Q/A2= (48+30) × 10⁻³ / 0.95= 0.089 m/s[/tex]
Therefore, the velocity in m/s at point 2 is 0.089 m/s.

Separation of household scheduled waste has not yet been enforced in Malaysia. Based on your opinion, estimate the suitable year to enforce and explain the reasons.
The best suitable year for household estimate in Malaysia is 2025 by this 45 % of recycling rate will increase.
Introduction:
In recent years, Malaysia has faced environmental challenges caused by municipal solid waste, especially household waste, during the COVID-19 pandemic. Among all the household waste, plastic and paper are the most unmanaged waste that cause environmental issues. Several recycling associations in Malaysia have carried out their practices for better waste sustainability and management to curb the increasing amount of household waste. Municipal solid waste (MSW) is the waste generated, collected, transported, and disposed of within the jurisdiction of a municipal authority.
For example, MSW generally consists of biodegradable materials, or construction waste. The management of solid waste is the most significant task faced by the authorities in developing nations’ small and major cities, and the municipal waste management budget has increased due to the increasing generation of such solid waste.
Solution:
Based on a report on Malaysia's waste collection data, there has been a significant increase in waste generation in recent years. In 2018, about 36,843 tonnes of waste were generated daily; 2019 (37,462); 2020 (38,081); 2021 (38,699); and 2022 (39,936). The best suitable year for household estimate 2025 by this 45 % of recycling rate will increase.
Reason:
Household waste is waste that is generated from the residential environment, it consists of household daily disposal of any type of material and is also known as domestic waste. Managing household waste including waste collection, transportation, and treatment is a global problem, whereby circular economy and recycling have to be promoted. Among all types and categories of household waste, plastic is ranked as the thirdlargest waste contributor globally due to its functionality and versatility. The world produces more than 400 million tons of plastics every year. The recent data estimated that only about 9% of the world’s plastic waste had been recycled, whereas most of the plastic waste (79%) is dumped in the landfills or open environment, followed by 12% incinerated. Malaysia is ranked 8th among the top ten countries globally due to the mismanagement of plastic waste (an estimated 0.94 million tons were produced).
According to nearly 40% of plastics produced globally are commonly used for packaging that we account for in our everyday lives, and they are designed for single-use and immediate disposal. The dumped plastic waste will mainly result in landfills, open environments, or lingering on the ocean surface or beaches. In Malaysia’s market segment, packaging stood the highest (48%) in the plastic market share as compared to plastic use in other industries. It was proven that Malaysia still relies heavily upon plastic packaging as part of its economic support.
Future household waste in Malaysia:
Malaysia is categorized as an upper-middle-income country, and the waste generation among all upper-middle-income countries is expected to increase from 655 million tons to 1004 million tons by 2050. Furthermore, the production of residential wastes depends upon the economy and size of the residential area. The higher the income value and larger the residential area, the more production of household wastes and waste management issues . The condition worsens when packaging waste has penetrated the e-commerce industry.
Conclusion:
Sustainable cities in Malaysia practice waste management with the integrated framework of future-proofing household waste management are believed to be an actionable quest for Malaysians, particularly in technology and data with the DSS model that offers smart solutions for tracking, collecting, and analyzing waste through ICT. It will create smart and efficient waste management solutions for citizens in saving time and energy to understand the waste types and study how to manage waste in their municipalities.
Business owners must play their part to be more responsible for their production and the consequences that may impact the environment and the government plays the role of making sure the rules and policy are strict and actionable enough based on the current situation.

A piping system consists of parallel pipes as shown in the following diagram. Both pipes are made of cast iron. The pipes are transporting water at 20oC. The total flow rate is 4 m3/s. Find the flow rate in the smaller pipe. There is no elevation change. Neglect minor losses.
The pipe system consists of two parallel pipes, both made of cast iron, transporting water at 20°C, and with a total flow rate of 4m³/s. We need to determine the flow rate in the smaller pipe. We can apply the equation of continuity to solve for the required flow rate. Conservation of mass in a pipe system is governed by the principle of continuity.
The principle of continuity, also known as the conservation of mass, states that the mass of water flowing into the system is equal to the mass of water flowing out of it. The continuity equation is expressed mathematically as:A1V1 = A2V2, where A is the cross-sectional area and V is the velocity.
We can re-write the continuity equation as Q = VA, where Q is the volumetric flow rate, which is equal to the product of velocity and area. The volumetric flow rate, or Q, is equal to the total flow rate of the pipes. Let's use subscript 1 to denote the larger pipe and subscript 2 to denote the smaller pipe. We have the following information:
Q = 4 m³/sQ = Q₁ + Q₂A₁ = πD₁²/4A₂ = πD₂²/4D₁ = 200 mm = 0.2 mD₂ = 100 mm = 0.1 m Substituting the given values into the continuity equation, we obtain: Q = Q₁ + Q₂ ⇒ 4 = Q₁ + Q₂ Since both pipes are transporting water at the same temperature and the elevation changes are negligible, the major losses in both pipes are the same.
We can thus assume that the velocity head losses are equal in both pipes. Therefore, the pressure drop in each pipe will be proportional to its length and to the square of the velocity. We can express this mathematically as follows:ΔP = K(V²/2g)L, where ΔP is the pressure drop, K is a friction factor, V is the velocity.

The Schottky defect has no effect on the overall crystal volume. This is due to the fact that the vacancy site of one cation or anion is matched with a vacancy site of another cation or anion, resulting in no net change in volume.
The Frenkel defect, on the other hand, results in an overall decrease in crystal volume. In ceramics, a type of Frenkel defect known as the Schottky defect occurs. In this type of defect, an ion migrates from its original position to an interstitial position. This causes the surrounding atoms to be pulled closer together, resulting in an overall decrease in crystal volume.

Pa at the top to 14.5 kPa at the fixed base of the wall. Consider 1-meter length and use modulus of elasticity of wood as 8.5 x 〖10〗^3 MPa. If the wall is propped at the top, determine the lateral force (kN) at the fixed end.Propping the wall at the top means that there is a support of some sort that is preventing the wall from moving in that direction. As a result, the amount of lateral force exerted at the fixed end will be equal to the amount of lateral force that would have been applied to the top, had it not been propped.
In this case, the lateral force (F) can be calculated using the formula: F = (1/2)γH² + (1/3)αH³where γ is the unit weight of the soil, H is the height of the soil, α is the pressure coefficient. The formula for pressure coefficient is:α = (1 - sinϕ)/(1 + sinϕ)where ϕ is the angle of friction. If the wall is propped at the top, then the lateral force will be: [tex]F = (1/2)γH² + (1/3)αH³Where H = 3 mα = (1 - sin(0))/(1 + sin(0)) = 0γ = 14.5/1000 = 0.0145 MPa F = (1/2) × 0.0145 × 3² + (1/3) × 0 × 3³F = 0.1305 kN[/tex]The lateral force at the fixed end will be 0.1305 kN.

A channel has a flange width of 100 mm and thickness of 2.5 mm
with a web of 250 250 mm and thickness of 2.5 mm. What is the
location of the shear center from the center of the web
section.
The shear center of a structural section refers to the point about which pure shear loads can be applied without causing any twisting of the section. When a shear load is applied to a section, two kinds of stress develop: axial stress and transverse shear stress.
If these two stresses are not equal and opposite, twisting will occur, and the shear center will not be at the centroid of the section. The formula to determine the location of the shear center is as follows:
Q = (Aw2 - Bf2) / (2Aw)Q = Distance between the shear center and the centroid of the section
Aw = Area of the webBf = Width of the flangeThe section is a channel with a flange width of 100 mm and thickness of 2.5 mm, and a web of 250 250 mm and thickness of 2.5 mm. The area of the web is 250 x 2.5 = 625 mm². The area of both flanges is 2 x (100 x 2.5) = 500 mm². Therefore, the total area of the section is 625 + 500 = 1125 mm².
The distance between the centroid of the section and the flange is half of the thickness of the web. So the distance from the centroid to the top of the web is 125 mm. The distance from the shear center to the centroid of the section (Q) can now be calculated.

For the selection of friction factor, f from the Moody diagram, select the most appropriate answer. O For smooth-walled pipes, we need to know Re only. O All the answers are correct. For laminar flow, we need to know Re only. O For rough turbulent flow, we need to know Re vs k/D.
The most appropriate answer is "For rough turbulent flow, we need to know Re vs k/D" for the selection of friction factor, f from the Moody diagram. A friction factor is an essential term used in fluid dynamics and hydrodynamics to calculate the pressure drop or head loss caused by friction of a fluid moving through a pipe.
Friction factor is a dimensionless term. It is used to determine the fluid's resistance to flow in the pipe network or channel. The choice of friction factor, f, determines the accuracy of the calculations. Friction factor, f, can be chosen using different methods. The most common method used for selecting f is by using the Moody diagram.
For laminar flow, we need to know Re only. For smooth-walled pipes, we need to know Re only. But for rough turbulent flow, we need to know Re vs k/D. The Reynolds number (Re) is a dimensionless quantity that represents the ratio of the inertial forces to the viscous forces.
The friction factor (f) depends on the Reynolds number and the relative roughness of the pipe (k/D). The relative roughness (k/D) is the ratio of the average roughness height to the pipe's internal diameter. The friction factor (f) can be selected from the Moody diagram by plotting the Reynolds number (Re) against the relative roughness (k/D) and reading the value of f from the chart.

In Super Bowl I, on January 15, 1967, the Green Bay Packers defeated the Kansas City Chiefs by a score of 35 to 10. The total points scored came from a combination of touchdowns, extra-point kicks and field goals, worth 6, 1, and 3 points respectively. The numbers of touchdowns and extra-point kicks were equal. There were six times as many touchdowns as field goals. (Source: NFL) Set up a system of linear equations to find the numbers of touchdowns, extra-point kicks, and field goals that were scored. Solve the system using Gauss-Jordan method.
A system of linear equations consists of two or more linear equations that share variables and have to be resolved simultaneously. The Gauss-Jordan method is a mathematical technique for solving systems of linear equations. This technique involves performing elementary operations on the augmented matrix, which is the matrix representing the system of equations, to reduce it to an equivalent matrix with a row-reduced form.
Let's use the following variables:
T = number of touchdowns
E = number of extra-point kicks
F = number of field goals
According to the problem, we know that:
T + E = 5FT = 6F
Since the total number of points scored is 35 and there are three ways to score points, we can also write:
T * 6 + E * 1 + F * 3 = 35
Now we can put these three equations into an augmented matrix and use the Gauss-Jordan method to solve it:
[tex]\left[\begin{array}{ccccc}1&1&-5&0&0\\2&0&1&-6&0\\13&1&0&0&35\end{array}\right][/tex]
First, we subtract twice the first row from the second row to eliminate the 2 in the first column of the second row:
[tex]\left[\begin{array}{ccccc}1&1&-5&0&0\\2&0&1&-6&0\\1&-1&1&0&25\end{array}\right][/tex]
Then we add row 2 to row 1 to eliminate the -1 in the first column of the third row:
[tex]\left[\begin{array}{ccccc}1&0&-4&-6&0\\2&0&1&-6&0\\1&0&-1&1&-3\end{array}\right][/tex]
Finally, we add four times the third row to the first row to eliminate the -4 in the first column of the first row:
[tex]\left[\begin{array}{ccccc}1&0&0&-10&8\\2&0&1&-6&0\\1&0&-1&1&-3\end{array}\right][/tex]
The solution to the system of equations is:
T = 8E = -3F = 2Therefore, 8 touchdowns, 8 extra-point kicks, and 2 field goals were scored.

Calculate the energy loss due to friction using:
1. Hazen-William equation
2. Scooby equation
3. Darcy-Weisbach equation Use the Churchill equation and then Moody curves to determine the coefficient of friction
When water flows through a pipe, it encounters friction which causes the energy of water to dissipate. The energy loss due to friction is an important factor that must be taken into account in any engineering calculations. The energy loss due to friction can be calculated using the Hazen-William equation, Scooby equation, and Darcy-Weisbach equation.
We will use the Churchill equation and then Moody curves to determine the coefficient of friction. Given data: Length of pipe (L) = 250 m Diameter of pipe (d) = 120 mm = 0.12 mWater flow rate (Q) = 20 litres/sec = 0.02 m3/secHazen-William equation The Hazen-William equation is given by: ƒ = 0.2083 × (C)1.85 × (d)-4.87 × (L)-1.85Where ƒ is the friction factor, C is the Hazen-Williams coefficient, d is the diameter of the pipe, and L is the length of the pipe.
The Hazen-Williams coefficient for polyethylene pipes is 150. We can substitute the given values to calculate the friction factor as follows: ƒ = 0.2083 × (150)1.85 × (0.12)-4.87 × (250)-1.85ƒ = 0.0191The energy loss due to friction can be calculated using the following formula: ΔE = ƒ × (L/d) × (ρ/2) × (v2)
Where ΔE is the energy loss due to friction, L/d is the length to diameter ratio, ρ is the density of water, and v is the velocity of water. The density of water is 1000 kg/m3.
The velocity of water can be calculated as follows: v = Q/A Where A is the cross-sectional area of the pipe. The cross-sectional area of the pipe can be calculated as follows: A = (π/4) × (d)2A = (π/4) × (0.12)2A = 0.0113 m2v = Q/A = 0.02/0.0113 = 1.77 m/s Substituting the given values in the formula, we get:
ΔE = 0.0191 × (250/0.12) × (1000/2) × (1.77)2ΔE = 4097.5 Joules Scooby equation The Scooby equation is an empirical equation used to calculate the friction factor.
It is given by: 1/√ƒ = 2.0 × log10(3.7 × d/ε) + 1.74/Re0.9
Where ε is the roughness of the pipe, and Re is the Reynolds number. The roughness of polyethylene pipes is 0.0001 mm. The Reynolds number can be calculated as follows: Re = (ρ × d × v)/μWhere μ is the dynamic viscosity of water. The dynamic viscosity of water is 0.001 N-s/m2.

The relationship among normal stress, load, cross-sectional area, and the Young's modulus of elasticity is expressed by the following equation:σ= PL/AEWhere,σ = normal stress P = Load L = Length A = Cross-sectional area
E = Young's modulus of elasticity In order to find the radius of the steel rod, we must first convert the load from kN to N.1 kN = 1000 N. Therefore, 9.17 kN = 9.17 × 1000 = 9170 N. Substituting the values of the given variables into the above equation, we get:
σ= (9170 N × 5.86 m)/(πr² × 199.1 × 10⁹ N/m²)We can simplify the above equation to obtain:r² = (π × (5.86 m)² × (188 × 10⁶ N/m²))/(9170 N × 199.1 × 10⁹ N/m²)r² = 0.0000020880m²
