Answer:

L = 10.32 m

Explanation:

The resistance of a copper-nickel alloy wire is given by the following formula:

\(R = \frac{\rho L}{A}\)

where,

R = Resistance = 0.5 Ω

ρ = resistivity of copper-nickel alloy = 3.8 x 10⁻⁸ Ωm

L = Length of wire = ?

A = cross-sectional area of wire = \(\frac{\pi d^2}{4} = \frac{\pi(1\ x\ 10^{-3}\ m)^2}{4}\) = 7.85 x 10⁻⁷ m²

Therefore,

\(0.5\ \Omega = \frac{(3.8\ x\ 10^{-8}\ \Omega.m)L}{7.85\ x\ 10^{-7}\ m^2}\)

L = 10.32 m

Answer:

For water

Flow rate= 0.79128*10^-3 Ns

For Air

Flow rate =1.2717*10^-3 Ns

Explanation:

For the flow rate of water in pipe.

Area of the pipe= πd²/4

Diameter = 30/1000

Diameter= 0.03 m

Area= 3.14*(0.03)²/4

Area= 7.065*10^-4

Flow rate = 7.065*10^-4*1.12E-3

Flow rate= 0.79128*10^-3 Ns

For the flow rate of air in pipe.

Flow rate = 7.065*10^-4*1.8E-5

Flow rate =1.2717*10^-3 Ns

Answer:

a) 764.45K

b) 210.48 kJ/kg

c) 30.14%

Explanation:

pressure ratio = 10

minimum temperature = 295 k

maximum temperature = 1240 k

isentropic efficiency for compressor = 83%

Isentropic efficiency for turbine = 87%

a) Air temperature at turbine exit

we can achieve this by interpolating for enthalpy

h4 = 783.05 kJ/kg ( calculated in the background ) at state 4 using Table A-17  for  Ideal gas properties of air

T4 ( temperature at Turbine exit ) = 760 + ( 780 - 760 ) \((\frac{783.05-778.18}{800.13-778.18} )\) = 764.45K

b) The net work output

first we determine the actual work input to compressor

Wc = h2 - h1  ( calculated values )

     = 626.57 - 295.17 =  331.4 kJ/kg

next determine the actual work done by Turbine

Wt = h3 - h4  ( calculated values )

     = 1324.93 - 783.05 = 541.88 kJ/kg

finally determine the network output of the cycle

Wnet = Wt - Wc

         = 541.88 - 331.4  = 210.48 kJ/kg

c) determine thermal efficiency

лth = Wnet / qin  ------ ( 1 )

where ; qin = h3 - h2

equation 1 becomes

лth = Wnet / ( h3 - h2 )

      = 210.48 / ( 1324.93 - 626.57 )

      = 0.3014  =  30.14%

A two-stage furnace can run at a predetermined output level that is either less than full heat or at maximum heat output.

Condensing furnaces are those that run with an AFUE of greater than 90%. This indicates that the furnace turns escaping water vapour back into energy and heat by condensing them. The furnace is therefore more effective than a noncondensing furnace.

The ability of a burner to burn fuel is indicated by the boiler's combustion efficiency. The amount of unburned fuel in the exhaust and the amount of extra oxygen in the exhaust are the two factors that influence the burner efficiency.

Answer:

The lateral stress ratio of the soil at point A is 0.3

Explanation:

given that; Unit weight = 20 kNm⁻³ at point A 5m below the ground surface,

vertical stress (\(V_{stress}\)) = 20 kNm⁻³ × 5m ⇒ 100 kNm⁻²

vertical stress (\(V_{stress}\)) = 100kPa

note that; Horizontal Stress (\(H_{stress}\)) is given by k(\(V_{stress}\))

where "k" is the lateral stress ratio

\(H_{stress}\) = k(\(V_{stress}\))

k = \(H_{stress}\) ÷ \(V_{stress}\)

k = 30 kPa ÷ 100 kPa

The type of strain that occurs when the differences in stress coming from different directions are low is called isotropic strain.

Isotropic strain refers to a type of strain that occurs when the stresses acting on a material are relatively equal in all directions. In other words, the material deforms uniformly under the influence of stress from various directions, resulting in equal strain in all directions. This type of strain is commonly observed in materials that exhibit isotropic behavior, meaning their mechanical properties are the same in all directions.

When the differences in stress between different directions are low, the material experiences minimal resistance to deformation, and the strain is distributed evenly throughout the material. This isotropic behavior is often seen in amorphous materials or in polycrystalline materials with randomly oriented grains. In contrast, anisotropic materials have varying mechanical properties in different directions, leading to different magnitudes and orientations of strain when subjected to stress.

Understanding the type of strain, whether isotropic or anisotropic, is crucial in materials engineering and design, as it influences the material's response to external forces and helps determine its mechanical behavior and structural integrity.

The three methods used to find the real roots of the function are,

graphically, the quadratic formula, and by iteration.

The correct vales are;

(a) Graphically, the roots obtained are; x ≈ -1.629, and 5.629

(b) Using the quadratic formula, the real roots of the given function are; x ≈ -1.62589, x ≈ 5.62859

(c) Using three iterations, we have; the bracket is \(x_l\) = 5.625, and \(x_u\) = 6.25

Reasons:

The given function is presented as follows;

f(x) = -0.6·x² + 2.4·x + 5.5

(a) The graph of the function is plotted on MS Excel, with increments in the

x-values of 0.01, to obtain the approximation of the x-intercepts which are

the real roots as follows;

\(\begin{array}{|c|cc|}x&&f(x)\\-1.63&&-0.00614\\-1.62&&0.03736\\5.62&&0.03736 \\5.63&&-0.00614\end{array}\right]\)

Checking for the approximation of x-value of the intercept, we have;

\(x = -1.63 + \dfrac{0 - (-0.00614)}{0.0376 - (-0.00614)} \times (-1.62-(-1.63)) \approx -1.629\)

Therefore, based on the similarity of the values at the intercepts, the x-

values (real roots of the function) at the x-intercepts (y = 0) are;

x ≈ -1.629, and 5.629

(b) The real roots of the quadratic equation are found using the quadratic

formula as follows;

The quadratic formula for finding the roots of the quadratic equation

presented in the form f(x) = a·x² + b·x + c, is given as follows;

\(x = \mathbf{ \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}}\)

Comparison to the given function, f(x) = -0.6·x² + 2.4·x + 5.5, gives;

a = -0.6, b = 2.4, and c = 5.5

Therefore, we get;

\(x = \dfrac{-2.4\pm \sqrt{2.4^{2}-4\times (-0.6)\times 5.5}}{2\times (-0.6)} = \dfrac{-2.4\pm\sqrt{18.96} }{-1.2} = \dfrac{12 \pm\sqrt{474} }{6}\)

Which gives

The real roots are; x ≈ -1.62859, and x ≈ 5.62859

(c) The initial guesses are;

\(x_l\) = 5, and \(x_u\) = 10

The first iteration is therefore;

\(x_r = \dfrac{5 + 10}{2} = 7.5\)

\(Estimated \ error , \ \epsilon _a = \left|\dfrac{10- 5}{10 + 5} \right | \times 100\% = 33.33\%\)

\(True \ error, \ \epsilon _t = \left|\dfrac{5.62859 - 7.5}{5.62859} \right | \times 100\% = 33.25\%\)

f(5) × f(7.5) = 2.5 × (-10.25) = -25.625

The bracket is therefore; \(x_l\) = 5, and \(x_u\) = 7.5

Second iteration:

\(x_r = \dfrac{5 + 7.5}{2} = 6.25\)

\(Estimated \ error , \ \epsilon _a = \left|\dfrac{7.5- 5}{7.5+ 5} \right | \times 100\% = 20\%\)

\(True \ error, \ \epsilon _t = \mathbf{\left|\dfrac{5.62859 - 6.25}{5.62859} \right | \times 100\%} \approx 11.04\%\)

f(5) × f(6.25) = 2.5 × (-2.9375) = -7.34375

The bracket is therefore; \(x_l\) = 5, and \(x_u\) = 6.25

Third iteration

\(x_r = \dfrac{5 + 6.25}{2} = 5.625\)

\(Estimated \ error , \ \epsilon _a = \left|\dfrac{5.625- 5}{5.625+ 5} \right | \times 100\% = 5.88\%\)

\(True \ error, \ \epsilon _t = \mathbf{\left|\dfrac{5.62859 - 5.625}{5.62859} \right | \times 100\%} \approx 6.378 \times 10^{-2}\%\)

f(5) × f(5.625) = 2.5 × (0.015625) = 0.015625

Therefore, the bracket is \(x_l\) = 5.625, and \(x_u\) = 6.25

Solution:-

- The shell and tube heat exchanger are designated by the order of tube and shell passes.

- A single tube pass: The fluid enters from inlet, exchange of heat, the fluid exits.

- A multiple tube pass: The fluid enters from inlet, exchange of heat, U bend of the fluid, exchange of heat, .... ( nth order of pass ), and then exits.

- By increasing the number of passes we have increased the "retention time" of a specific volume of tube fluid; hence, providing sufficient time for the fluid to exchange heat with the shell fluid.

- By making more U-turns we are allowing greater length for the fluid flow to develop with " constriction and turns " into turbulence. This turbulence usually at the final passes allows mixing of fluid and increases the heat transfer coefficient by:

                                U ∝ v^( 0.8 )    .... ( turbulence )

- The higher the velocity of the fluids the greater the heat transfer coefficient. The increase in the heat transfer coefficient will allow less heat energy carried by either of the fluids to be wasted ; hence, reduced losses.

Thereby, increases the thermal efficiency of the heat exchanger ( higher NTU units ).

During a full anneal heat treatment, the desired temperature for heating iron-carbon alloys depends on their carbon content. Here are the approximate temperatures for each alloy:

(a) 0.25 wt% C: Around 727°C [tolerance is +/-596°C]

(b) 0.45 wt% C: Approximately 727°C [tolerance is +/-596°C]

(c) 0.85 wt% C: Roughly 760°C [tolerance is +/-596°C]

(d) 1.10 wt% C: About 740°C [tolerance is +/-5%]

(a) 0.25 wt% C: At this carbon content, the alloy is considered a low-carbon steel. The approximate temperature for a full anneal heat treatment is around 727°C. This temperature allows for the formation of a fine-grained microstructure and the elimination of internal stresses in the material.

(b) 0.45 wt% C: This carbon content falls within the range of medium-carbon steel. Similar to the previous alloy, the approximate temperature for a full anneal heat treatment is around 727°C. The purpose of annealing is to refine the microstructure, enhance ductility, and reduce hardness in the material.

(c) 0.85 wt% C: With this carbon content, the alloy is considered a high-carbon steel. The approximate temperature for a full anneal heat treatment is roughly 760°C. The higher carbon content requires a slightly elevated temperature to achieve the desired transformation and improve the material's machinability and workability.

(d) 1.10 wt% C: This carbon content indicates a hypereutectoid steel, which means it has more carbon than is soluble in the iron matrix. The approximate temperature for a full anneal heat treatment is about 740°C. Annealing at this temperature allows for the formation of a microstructure consisting of coarse pearlite, which provides improved strength and wear resistance.

Explanation:

Step 1: Calculate the molecular weight of the monomer

Polyethilene is a polymer with the formula (C₂H₄)ₙ, where C₂H₄ is the monomer and n is the number of monomers in the polymer. We can calculate the molecular weight of the monomer by addition of the weights of the atoms that form it.

MC₂H₄ = 2 × MC + 4 × MH

MC₂H₄ = 2 × 12 + 4 × 1 = 28

Step 2: Calculate the average molecular weight of polyethylene

The average degree of polymerization (DP) of polyethylene is 12,000. We can calculate the average molecular weight of polyethylene using the following expression.

DP = M(C₂H₄)ₙ/MC₂H₄

M(C₂H₄)ₙ = DP × MC₂H₄

M(C₂H₄)ₙ = 12,000 × 28 = 336,000
