Question A.1 A steam power plant operates on an ideal reheat regenerative Rankine cycle with two turbine stages, one closed feed water heater and one open feed water heater. Steam is superheated and supplied to the high-pressure turbine at 200 bar and 700 °C. Steam exits at 30 bar and a fraction of it is bled to a closed feed water heater. The remaining steam is reheated in the boiler to 600°C before entering the low-pressure turbine. During expansion in the low- pressure turbine, another fraction of the steam is bled off at a pressure of 2 bar to the open feed water heater. The remaining steam is expanded to the condenser pressure of 0.2 bar. Saturated liquid water leaving the condenser is pumped to the pressure of the open feed heater. Water leaving this is then pumped through the closed feed heater and mixed with the pumped cross flow bled steam. The whole of the water is returned to the boiler and superheater and the cycle is repeated. i) Starting with state 1 at the entrance to the high-pressure turbine, draw a fully annotated schematic diagram of the steam power plant, and a sketch an accompanying temperature - specific entropy diagram. (10 Marks) ii) Plot on the supplied enthalpy - entropy steam chart (Mollier diagram) states 1 to 5 and the process lines for steam expansion through the high-pressure turbine, reheat through the boiler, and expansion to the condenser pressure. Clearly mark on the chart all state properties. Ensure that you include the annotated steam chart along with your solutions to obtain relevant marks for the above question part. (10 Marks) iii) Determine the fractions of steam extracted from the turbines and bled to the feed heaters. State all assumptions used and show all calculation steps. (10 Marks) iv) Calculate the thermal efficiency of the plant and the specific steam consumption, clearly stating all assumptions. (10 Marks) v) Explain why the thermal efficiency of the steam cycles may be increased through use of regenerative feed heaters. Make use of suitable sketches and clearly identify the main thermodynamic reasons. [10 Marks]

Answer: the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Explanation:

Given that;

Weight of soil r = 118 lb/ft³

stress parameter C = 250 lb/ft²

φ total = 29°

depth Z = 12 ft

The shear strength on a horizontal plane at a depth of 12ft

ζ = C + δtanφ

where δ = normal stress

normal stress δ = r × z = 118 × 12 = 1416

so

ζ = C + δtanφ

ζ = 250 + 1416(tan29°)

ζ = 250 + 1416(tan29°)

ζ = 250 + 784.9016

ζ = 1034.9015 lb/ft²

Therefore the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Answer: Ethanol

Explanation:

Answer:

The two values of x are 2n*pi + pi/12 and 2n*pi -5pi/12

Explanation:

The given equation is

Sin x +√3 Cosx= √2

Upon dividing the equation by 2 we get

 \(\frac{1}{2}Sinx + \frac{\sqrt{3} }{2}Cosx = \frac{\sqrt{2} }{2}\)

Sin(\(\frac{pi}{6}\))*Sinx + Cos(\(\frac{pi}{6}\))*Cosx = \(\frac{1}{\sqrt{2} }\)

This makes the formula of

CosACosB + SinASinB = Cos(A-B)

 Cos(x-\(\frac{pi}{6}\)) = \(\frac{1}{\sqrt{2} }\)

cos(x- pi/6) = cos(pi/4)

upon writing the general equation we get

x-pi/6 = 2n*pi ± pi/4

x = 2n*pi ± pi/4 -pi/6

so we will have two solutions

x = 2n*pi + pi/4 -pi/6

  = 2n*pi + pi/12

and

x = 2n*pi - pi/4 -pi/6

  = 2n*pi -5pi/12

Therefore the two values of x are 2n*pi + pi/12 and 2n*pi -5pi/12.

Answer:

The answers are in the explanation. The pH is 5.91

Explanation:

The CH3NH2 reacts with HCl as follows:

CH3NH2 + HCl → CH3NH3⁺ + Cl⁻

When 200mL of HCl are added, the moles of CH3NH2 and HCl are reacting completely producing CH3NH3+ and Cl-. That means the species present are:

no H+. All reacted

yes H2O. Because the water is present in the solutions of HCl and CH3NH2

yes Cl-. Is a product of the reaction

Yes CH3NH2. Is consumed in the reaction but comes from the equilibrium of CH3NH3+

yes CH3NH3+. Is the other product of the reaction. MAJOR SPECIES

When 300.00mL of HCl are added, 100mL are in excess:

yes H+. Is in excess: H+ + Cl- = HCl in water. MAJOR SPECIES. Determine the pH of the solution.

yes H2O. Is present because the reactants are diluted.  

yes Cl-. Is a product of reaction and comes from HCl.

Yes CH3NH2. The reactant is over but comes from the equilibrium of CH3NH3+

yes no CH3NH3+. Yes. Is a product and remains despite HCl is in excess.

To find the pH:

At equivalence point the ion that determines pH is CH3NH3+. Its concentration is:

0.100L * (0.200mol/L) = 0.0200 moles / 0.300L = 0.0667M CH3NH3+

The equilibrium of CH3NH3+ is:

Ka = Kw/kb = 1x10-14/4.4x10-4 = 2.273x10-11 = [H+] [CH3NH2] / [CH3NH3+]

As both [H+] [CH3NH2] comes from the same equilibrium:

[H+] =  [CH3NH2] = X

2.273x10-11 = [X] [X] / [0.0667M]

1.5159x10-12 = X²

X = 1.23x10-6M = [H+]

As pH = -log [H+]

pH = 5.91

The pH at the equivalent point for this titration is "5.91".

\(CH_3NH_2 = 0.200\ M\\\\ \text{volume} = 100.0\ mL = 0.100\ L\\\\HCl = 0.100\ M\\\\\)

We must now quantify the pH well at the equivalence point.

We know that even at the point of equivalence, moles of acid and moles of the base are equivalent. As such, first, we must calculate the number of moles of the given base.

Calculating the Moles in \(CH_3NH_2 = 0.200\ M \times 0.100\ L = 0.0200\ moles\)

Calculating the Moles in \(HCl = 0.0200 \ moles\)

Calculating the volume of \(HCl\):

\(\to \text{Molarity} = \frac{ \text{moles}}{\text{volume \ (L)}} \\\\\to \text{Volume} = \frac{\text{moles}}{\text{molarity}}\\\\\)

                \(= \frac{0.0200 \ moles}{ 0.100\ M}\\\\= 0.200 \ L\\\\= 200 \ mL\\\\\)

Calculating the reaction among the acid and base:

\(CH_3NH_2 + HCl \longrightarrow CH_3NH_3^{+} + Cl^-\)

\(0.0200 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.0200 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.0200\)

Therefore the conjugate acid of the bases exists at the standard solution.

Then we must calculate the new molar mass of \(CH_3NH_3^+\).

Total volume\(= 100 + 200 = 300\ mL = 0.300\ L\)

\([CH_3NH_3^+] = \frac{0.0200\ mole}{ 0.300\ L}= 0.0667\ M\)

Using the ICE table

\(CH_3NH_3^+ + H_2O \longrightarrow CH_3NH_2 + H_3O^+\)

\(I \ \ \ \ \ \ \ \ \ \ 0.0667 \ \ \ \ \ \ \ \ \ 0\ \ \ \ \ \ \ \ \ 0\\\\C\ \ \ \ \ \ \ \ -x\ \ \ \ \ \ \ \ +x \ \ \ \ \ \ \ \ +x\\\\E \ \ \ \ \ \ \ \ \ \ \ \ 0.0667-x \ \ \ \ \ \ \ \ \ \ \ \ +x \ \ \ \ \ \ \ \ \ \ \ \+x\\\\\to Ka = \frac{[CH_3NH_2] [H_3O^+] }{[CH_3NH_3^+]}\)

Calculating \(K_a\) from \(K_b\)

\(\to K_a \times K_b = 1\times 10^{-14}\\\\\to K_a = \frac{1\times 10^{-14}}{4.4\times 10^{-4}} = 2.27\times 10^{-11}\\\\\)

                           \(= 2.27\times 10^{-11} \\\\= x\times \frac{x}{(0.0667-x)}\)

The x in the 0.0667-x can be ignored since the Ka value is just too small and it also does not follow the five percent criteria.

\(\to 2.27 \times 10^{-11} \times 0.0667 = x_2\\\\\to x_2 = 1.515\times 10^{-12}\\\\\to x = 1.23\times 10^{-6}\ M\\\\\to [H_3O^+] = x = 1.23\times 10^{-6}\ M\\\\\)

We have the formula to calculate pH.

\(\to pH = - \log [H_3O^+] = - \log 1.23\times 10^{-6}\ M= 5.91\)

The pH at the equivalent point for this titration is "5.91".

Answer:

a) The current in the heating element when it is connected to 120 V is 9.229 amperes, b) The power received by the heatng element connected to 120 V is 1107.522 watts.

Explanation:

a) The resistance as a function of voltage and power can be obtained from this expression, derived from the Ohm's Law:

\(\dot W = \frac{V^{2}}{R}\)

Where:

\(V\) - Source voltage, measured in volts.

\(R\) - Heating element resistance, measured in ohms.

Now, resistance is clear and determined afterwards:

\(R = \frac{V^{2}}{\dot W}\)

If \(V = 240\,V\) and \(\dot W = 4,430\,W\), then:

\(R = \frac{(240\,V)^{2}}{4.430\,W}\)

\(R = 13.002\,\Omega\)

Now, let consider that heating element is conected to a 120-V source. The power generated by this element is:

\(\dot W = \frac{V^{2}}{R}\)

\(\dot W = \frac{(120\,V)^{2}}{13.002\,\Omega}\)

\(\dot W = 1107.522\,W\)

Besides, power as a function of current and resistance is given by this:

\(\dot W = i^{2}\cdot R\)

Where \(i\) is the current required by the heating element, measured in amperes, and which is cleared herein:

\(i = \sqrt{\frac{\dot W}{R} }\)

If \(\dot W = 1107.522\,W\) and \(R = 13.002\,\Omega\), then:

\(i = \sqrt{\frac{1107.522\,W}{13.002\,\Omega} }\)

\(i \approx 9.229\,A\)

The current in the heating element when it is connected to 120 V is 9.229 amperes.

b) The power received by the heatng element connected to 120 V is 1107.522 watts. (see point a) for further details)

The correct option for the implication of low variety is B) Flexibility needed. Variety refers to the number of different products, services, or activities that an organization offers. High variety means that a company offers a wide variety of products or services, while low variety means that a company provides a limited range of products or services.

One of the implications of low variety is that customers have limited options. They are restricted to purchasing only those goods and services that the company offers, which may not match their requirements or preferences. This may lead to losing customers to rivals who offer a greater variety of goods and services.

In the case of low variety, it is critical to have the required flexibility. Customers may ask for certain specific goods or services that are not provided by the company. To meet customer requirements, the company should be adaptable and able to rapidly respond to customer requests by expanding its product line. As a result, low variety necessitates the need for flexibility.

The other given options are not valid. Low unit cost is not related to low variety. Unit cost may be affected by economies of scale and other factors, but it is not directly related to variety. High complexity is not related to low variety as well. As the range of goods and services offered by the company increases, the complexity of the company's operations and management also increases. Matching customers' specific needs is partially correct because the company cannot match customer specific needs in low variety. In low variety, the company has a limited range of goods and services, so it is not possible to fulfill all the customers’ specific needs.

If 60% of the encryption operations can be performed in parallel in the original program, then adding a second unit would provide a speedup of 20 on the encryption operation portion that can be parallelized. This is because the second unit allows for the parallel execution of the encryption operations, resulting in a reduction of the execution time.

On the other hand, if the parallelization is limited to the number of encryption units, providing four encryption units would provide a speedup of 10 on the operation portion that cannot be parallelized. This is because the addition of two more units would not increase the parallelization of the encryption operations that are not parallelizable.

Therefore, if the goal is to speed up the encryption operation as much as possible, adding a second unit to support parallel encryption operations would be more useful as it would provide a speedup of 20 on the encryption operation portion that can be parallelized.

The addition of a second unit to facilitate parallel encryption operations would be more beneficial if the goal is to accelerate the encryption process.

If 60% of the encryption processes in the original program can be carried out in parallel, adding a second unit would result in a speedup of 20 for that portion of the encryption procedures that can be parallelized.

This is so that the execution time can be decreased by doing the encryption procedures in parallel using the second unit.

The provision of four encryption units would result in a 10x speedup on the operation portion that cannot be parallelized, however, assuming the number of encryption units is the only constraint on parallelization.

This is so that the parallelization of the encryption processes that cannot be parallelized would not be increased by the addition of two more units.

Therefore, if the intention is to speed up the encryption process, adding a second unit to enable parallel encryption operations would be more advantageous.

Mean Time Between In-Flight Shutdowns (MTBIFSD) is a measure used in aviation to quantify the reliability of an aircraft engine. It represents the average operating time between consecutive in-flight engine shutdowns due to failures or malfunctions.

MTBIFSD is an important metric that reflects the reliability and performance of an aircraft engine in real-world conditions.

b) The basic elements of a Reliability Programme include:

Reliability Engineering: This involves analyzing and understanding the reliability characteristics of the system or component under consideration. It includes activities such as failure data analysis, reliability prediction, and modeling.

Failure Reporting, Analysis, and Corrective Action System (FRACAS): FRACAS is a process that collects, analyzes, and addresses failures or malfunctions of components or systems. It involves recording and tracking failure data, investigating root causes, and implementing corrective actions to improve reliability.

Reliability Testing: Reliability testing is conducted to assess the performance and durability of a system or component under various operating conditions. It involves subjecting the system to stress tests, environmental tests, and other specialized tests to identify potential failure modes and assess reliability.Maintenance and Support: An effective Reliability Programme includes maintenance strategies to ensure the reliability and availability of the system. This includes preventive maintenance, scheduled inspections, and proactive component replacements based on reliability analysis and predictions.

Several factors could cause a transmission to not hold in park. Some possible causes include:

Faulty or worn-out parking pawl: The parking pawl is a small metal pin that engages with the transmission's output shaft to prevent it from rotating when the vehicle is in park. If the pawl is damaged, worn, or improperly engaged, it may not effectively hold the transmission in place.

Malfunctioning shift linkage: The shift linkage connects the gear shift lever to the transmission. If the linkage is misaligned, loose, or damaged, it may not fully engage the park position, causing the transmission to slip out of park.

Low transmission fluid level: Insufficient transmission fluid can affect the hydraulic pressure necessary to engage the parking pawl effectively. If the fluid level is too low, it may result in the transmission not holding in park.
