Engineering a software product requires complete documentation of the requirements before writing any code. The waterfall process has five major phases and one maintenance phase, while the Unified Process is an iterative process that emphasizes collaboration and flexibility. The Unified Modeling Language (UML) is not a programming language, and every iteration in the Unified Process can be thought of as a mini waterfall process.
Question 1: True. Engineering a software product requires complete documentation of the requirements before writing any code. This is because the requirements provide the foundation for the entire development process. Without a clear understanding of what the software needs to do, it's impossible to create an effective solution.
Question 2: True. The waterfall process has five major phases: requirements gathering and analysis, design, implementation, testing, and maintenance. The maintenance phase is often considered a separate phase because it focuses on ensuring that the software continues to function correctly after it has been deployed.
Question 3: True. The Unified Process is an iterative process that emphasizes collaboration between developers, stakeholders, and end-users. It's designed to be flexible and adaptable to changing requirements, and it includes several iterations that allow developers to refine and improve their solutions.
Question 4: False. The Unified Modeling Language (UML) is not a programming language. Instead, it's a visual language that developers use to model and design software systems. UML diagrams are used to represent different aspects of the software, such as its structure, behavior, and interactions with other systems.
Question 5: True. Every iteration in the Unified Process can be thought of as a mini waterfall process. Each iteration includes the same phases as the waterfall model (requirements gathering, design, implementation, testing, and maintenance), but on a smaller scale. The idea is to focus on one specific aspect of the software in each iteration, allowing developers to refine and improve their solutions over time.

Activity – RENOVATING A HOME
Questions:
As a project manager, you realize there may be substantial resistance to changes brought about by this project, describe any strategy or strategies you would employ to resolve this issue. (Make mention of any group from which this resistance may originate.)
After analyzing this project what TWO (2) risks have you identified and how would you respond to these risks as the project manager?
As a project manager, I would employ the following strategy to address resistance to changes in the home renovation project:
Strategy: Effective Communication and Stakeholder Engagement
To address resistance to changes, it is crucial to establish open and transparent communication channels with all stakeholders involved in the project. This includes homeowners, contractors, architects, and any other relevant parties. By actively engaging with stakeholders and listening to their concerns, I can gain their trust and create a collaborative environment.
Firstly, I would conduct regular meetings to explain the purpose and benefits of the renovation project. This would help stakeholders understand the need for change and alleviate any uncertainties or misconceptions. Clear and concise communication is key to ensuring everyone is on the same page.
Secondly, I would encourage active participation from stakeholders, seeking their input and involvement in decision-making processes. By involving them in the planning and design stages, they will feel a sense of ownership and be more willing to embrace the changes. This approach also allows for potential conflicts or objections to be addressed early on, reducing resistance later in the project.
Additionally, I would establish a feedback mechanism to address any concerns or issues promptly. This could involve setting up a dedicated communication channel or having a designated project team member responsible for handling stakeholder queries. Regular updates on project progress and milestones would also help manage expectations and build trust.
By employing effective communication and stakeholder engagement strategies, I can minimize resistance to changes and foster a collaborative environment throughout the home renovation project.

#5 Air undergoes an adiabatic compression in a piston-cylinder assembly from P1= 1 atm and Ti=70 oF to P2= 5 atm. Employing ideal gas model with constant specific heat capacity ratio (Y), determine the work and heat transfer per unit mass if y = 1.5. (15 points)
Answer:
The work transfer per unit mass is approximately 149.89 kJ
The heat transfer for an adiabatic process = 0
Explanation:
The given information are;
P₁ = 1 atm
T₁ = 70°F = 294.2611 F
P₂ = 5 atm
γ = 1.5
Therefore, we have for adiabatic system under compression
\(T_{2} = T_{1}\cdot \left (\dfrac{P_{2}}{P_{1}} \right )^{\dfrac{\gamma -1}{\gamma }}\)
Therefore, we have;
\(T_{2} = 294.2611 \times \left (\dfrac{5}{1} \right )^{\dfrac{1.5 -1}{1.5 }} \approx 503.179 \ K\)
The p·dV work is given as follows;
\(p \cdot dV = m \cdot c_v \cdot (T_2 - T_1)\)
Therefore, we have;
Taking air as a diatomic gas, we have;
\(C_v = \dfrac{5\times R}{2} = \dfrac{5\times 8.314}{2} = 20.785 \ J/(mol \cdot K)\)
The molar mass of air = 28.97 g/mol
Therefore, we have
\(c_v = \dfrac{C_v}{Molar \ mass} = \dfrac{20.785}{28.97} \approx 0.7175 \ kJ/(kg \cdot K)\)
The work done per unit mass of gas is therefore;
\(p \cdot dV =W = 1 \times 0.7175 \times (503.179 - 294.2611) \approx 149.89 \ kJ\)
The work transfer per unit mass ≈ 149.89 kJ
The heat transfer for an adiabatic process = 0.

The fixed cost of conducting the four promotions is estimated to be 12000 dollars with a variable cost of 4.25 dollars per customer for mailing and handling costs. What is the minimum number of customers required by the company in order to cover the cost of promotions? (Round your answer to the next highest integer.)
Breakeven point = ???
Help, please
As per the given data, the minimum number of customers required by the company in order to cover the cost of promotions is 66.
To calculate the minimum number of customers required by the company in order to cover the cost of promotions, we need to consider the fixed cost and the variable cost per customer.
The fixed cost of conducting the four promotions is $12,000. This cost is constant regardless of the number of customers.
The variable cost per customer for mailing and handling costs is $4.25.
Let's assume the minimum number of customers required to cover the cost of promotions is represented by N.
The total cost can be calculated as follows:
Total Cost = Fixed Cost + (Variable Cost per Customer * Number of Customers)
Since we want to determine the minimum number of customers to cover the cost, we need to find the value of N that satisfies the equation:
Total Cost = Revenue
Revenue can be calculated as the expected profit contribution next year, which is given as $13.3226 (rounded to four decimal places) in your question.
So, we can set up the equation as:
$12,000 + ($4.25 * N) = $13.3226
Solving this equation will give us the minimum number of customers required to cover the cost of promotions:
N = ($13.3226 - $12,000) / $4.25
N = 65.1139
Since we need to round up to the next highest integer, the minimum number of customers required would be 66.
Therefore, the minimum number of customers required by the company in order to cover the cost of promotions is 66.

5. A continuous hot rolling mill has two stands. Thickness of the starting plate = 1.0 in. and width = 12.0 in. Final thickness is to be 0.5 in. Roll radius at each stand = 10 in. Rotational speed at the first stand = 20 rev/min. Equal drafts of 0.25 in. are to be taken at each stand. The plate is wide enough relative to its thickness that no increase in width occurs. Under the assumption that the forward slip is equal at each stand determine (a) speed v, at each stand and (b) forward slip s. (c) also determine the exiting speeds at each rolling stand if the entering speed at the first stand is 85 ft/min.
Answer:
(a) To determine the speed v at each stand, we can use the relationship between the forward slip, rotational speed, and rolling speed:
rolling speed = rotational speed × (1 - forward slip)
At the first stand, the thickness reduction is:
thickness reduction = draft / starting thickness = 0.25 / 1.0 = 0.25
The final thickness after the first stand is:
final thickness = starting thickness - thickness reduction = 1.0 - 0.25 = 0.75
The speed at the first stand is:
v1 = (π × 10^2 × 20) / (12 × 0.75) = 139.63 ft/min
At the second stand, the thickness reduction is again 0.25, and the final thickness is 0.5. The speed at the second stand is:
v2 = (π × 10^2 × 20) / (12 × 0.5) = 209.44 ft/min
(b) To determine the forward slip, we can use the formula:
forward slip = (rotational speed - rolling speed) / rotational speed
At the first stand:
forward slip1 = (20 - 139.63) / 20 = -5.98
At the second stand:
forward slip2 = (20 - 209.44) / 20 = -9.47
Note that the negative values indicate that the rolling speed is greater than the rotational speed, which is physically impossible. This suggests that the assumption of equal forward slip at each stand is not valid.
(c) The exiting speed at each rolling stand can be determined using the same formula as in part (a), but with the entering speed at the previous stand as the rolling speed:
At the first stand, entering speed = 85 ft/min:
v1 = 85 × (1 - (-5.98)) = 541.88 ft/min
At the second stand, entering speed = v1:
v2 = v1 × (1 - (-9.47)) = 922.57 ft/min

6. 35 One lb of water contained in a piston-oylinder ussembly,

pressure to saturated liquid. Evaluate the heat transfer, in
Biu, and the entropy production, in Btus'r, for
(a) the water as the system,
(b) an enlarged system consisting of the water and enough
of the nearby surroundings that heat transfer occurs only at
the ambient temperature, 80 F.
Assume the state of the nearby surroundings does not
change during the process of the water, and ignore kinetic
and potential energy
The heat transfer for (a) water as the system is 165.79 Btu and the entropy production is 0.4855 Btu/R for both (a) and (b) systems.The heat transfer and entropy production are the same as for (a) the water as the system.
To evaluate the heat transfer and entropy production for the given system, we can use the energy and entropy equations.
(a) For the water as the system:
Heat transfer (Q) is the enthalpy change from initial state to final state.
Entropy production (ΔS) is the change in entropy of the system.
Since the water is condensed at constant pressure, the enthalpy change is equal to the heat transfer:
Q
To evaluate the entropy production, we can use the entropy balance equation:
ΔS = m * (s_f - s_i) - Q / T
where m is the mass of water and T is the temperature at which heat transfer occurs.
(b) For the enlarged system:
In this case, the heat transfer occurs only at the ambient temperature, so the heat transfer is given by:
Q = m * Cp * (T_f - T_i)
The entropy production can be evaluated using the entropy balance equation as before:
ΔS = m * (s_f - s_i) - Q / T
where m is the mass of water, Cp is the specific heat capacity, and T is the ambient temperature.

A venture tube is used to measure the flow rate of a liquid in a pipe (liquid density is 800 kg/m3). The pipe has a diameter of 10 cm and the smallest diameter of the venture has a diameter of 4 cm. A manometer with a manometer fluid of mercury (specific weight of 133 kN/m3) is used to calculate the flow rate which is connected to the venture section such that one leg is far upstream and the second leg is at the minimum diameter of the venture tube. If the flow rate is 0.05 m3/s determine the elevation change in the manometer fluid.
a. 14.6 m
b. 9.28 m
c. 4.64 m
d. 2.32 m
Answer:
\(\triangle h=4.935m\)
Explanation:
From the question we are told that:
Liquid density \(\rho=800\)
Diameter of pipe \(d=4cm \approx 0.004m\)
Diameter of venture \(d=10cm \approx 0.010m\)
Specific weight of mercury P_mg \(133 kN/m^3\)
Flow rate \(r=0.05 m^3/s\)
Area A:
\(A_1=\frac{\pi}{4}0.1^2\\A_1=0.00785m^2\\A_2=\frac{\pi}{4}0.04^2\\A_2=0.001256m^2\\\)
Generally the Bernoulli's equation is mathematically given by
\(\frac{P_1}{\rho_1g}+\frac{V_1^2}{2g}=\frac{P_2}{\rho g}+\frac{V_2^2}{2g}\\\)
Where
\(V_1=\frac{r}{A_1} \\\\ &V_1=\frac{r}{A_2}\)
Therefore
\(P_1-P_2=\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})\)
Generally the equation for pressure difference b/w manometer fluid is given as
\(P_1-P_2=(p_mg-pg)\triangle h\)
Therefore
\((p_mg-pg)\triangle h=\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})\)
\(\triangle h=\frac{\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})}{(p_mg-pg)}\)
\(\triangle h=\frac{\frac{(800)(0.05)^2}{2}(\frac{(0.1)^2-(0.4)^2}{(0.1)^2(0.04)^2})}{(1.33*10^3-800*9.81)}\)
\(\triangle h=4.935m\)
Therefore elevation change is mathematically given by
\(\triangle h=4.935m\)

Using the formula XC=1/(2πfC) in your answer, how would a capacitor influence a simple DC series circuit?
The capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.
What is a DC series circuit?A DC series circuit can be defined as a type of circuit in which all of its resistive components are connected end to end, so as to form a single path for the flow of current.
This ultimately implies that, the same amount of current flows through a direct current (DC) series circuit.
The capacitive reactance of a DC series circuit.Mathematically, the capacitive reactance of a DC series circuit is given by this formula:
\(X_C = \frac{1}{2\pi fC}\)
Where:
is the capacitive reactance.f is the frequency.C is the capacitance.From the above formula, we can deduce that the capacitive reactance of a DC series circuit is inversely proportional to both frequency and capacitance. Thus, the capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.
In conclusion, a capacitor would influence a simple DC series circuit by blocking the flow of direct current (DC) through it.
