A rigid, well-insulated tank contains a two-phase mixture consisting of 0.005 ft3 of saturated liquid water and 2.7 ft3 of saturated water vapor, initially at 14.7 lbf/in.2 A paddle wheel stirs the mixture until only saturated vapor remains in the tank. Kinetic and potential energy effects are negligible. For the water, determine the amount of energy transfer by work, in Btu.

A batter hits the baseball A with an initial velocity of v₀ = 97 ft/sec directly toward fielder B at an angle of 40° to the horizontal; the initial position of the ball is 2.0 ft above ground level. Fielder B requires 0.23 sec to judge where the ball should be caught and begins moving to that position with constant speed. Because of great experience, fielder B chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. Fielder B starts 234 ft from the batter. The catch position is the field location at which the ball altitude is 6.3 ft. Determine the velocity of the ball relative to the fielder at the instant the catch is made. Assume that the time needed for the fielder to achieve his velocity from the start point is negligibly small. Please state answer for time at catch postion as well

Manufacturing Process

3) It’s been more than 3 decades since the invention of Additive Manufacturing processes. However, still we cannot see introduction of many Additive Manufacturing products into the market. What is the reason behind this issue from your perspective?

discuss how moulded tiles on composite materials are manufactured, especially polypropylene(Pp) tiles (2000 words)

Describe the main functions of drive trains or power transmission systems used in a milling machine. Include references if you can so I research further into it :)

Describe in your own words with appropriate figures the Recovery, Recrystallization and Grain Growth in the heat treatment metallic materials after cold work.

In C++

c. The program should output the highest and lowest temperatures for the year. Your program must consist of the following functions:

a. Function getData: This function reads and stores data in the two-dimensional array.

b. Function indexHighTemp: This function returns the index of the highest high temperature in the array.

c. Function indexLowTemp: This function returns the index of the lowest low temperature in the array.

These functions must all have the appropriate parameters.

In c++

Write a program that uses a DYNAMIC two-dimensional array to store the highest and lowest temperatures for each month of the year (temperature is a decimal value). The program should output the highest and lowest temperatures for the year. Your program must consist of the following functions:

a. Function getData: This function reads and stores data in the two-dimensional array.

b. Function indexHighTemp: This function returns the index of the highest high temperature in the array.

c. Function indexLowTemp: This function returns the index of the lowest low temperature in the array.

These functions must all have the appropriate parameters.

Large thin metal sheets of length L are dipped in an electroplating bath in the vertical position. Their average temperature is initially cooler than the liquid in the bath. How rapidly will they come up to bath temperature, Tb? Now please take the time out to explain your answer in detail, as well as, list all steps that led to this final answer.

Assume that you are appointed by a university as the technical manager of the University's Formula-SAE-A Race Car project and you are required to:
a) Identify the relationships between operational objectives and functional requirements for the case of a new Formula-SAE-A Race Car (F-SAE-A) in 2018. Cite three operational objectives and the functional requirements that are needed to realise these objectives via using qualitative measures only; and
b) What is meant by “MOE”? For the effectiveness analysis of the F-SAE-A, list what you think would be the 10 most important characteristics that should be exercised and measured in the analysis. For one of the MOE of the F-SAE-A, describe an operational scenario for obtaining a measure of its effectiveness.

As a systems engineer, you are required to do a trade study on common coffeemakers available in market. Conduct product research and narrow down your choices to five products. Please conduct the following steps:

i. Develop a top - level function list for a common coffeemaker, limiting yourself to no more than 12 functions; ii. Draw an FBD of the coffeemaker using the functions in

(i); iii. Convert the coffeemaker FBD to an IDEF0 diagram and a UML activity diagram respectively;

iv. Identify exactly four selection criteria, not including purchase price or operating cost;

v. Assign weights to each criterion, explaining in one sentence your rationale;

vi. Construct a utility function for each criterion — describe it verbally or graphically; vii. Research the actual values for your criteria for each alternative; viii. Perform the analysis, calculating a weighted sum for each alternative;

ix. Calculate the effectiveness/unit cost for each alternative using purchase price for cost; and

x. Describe your choice for purchase, along with any rationale.

A nuclear fuel element is in the form of long solid cylindrical rod (k=0.85 W/mK) of diameter 14 mm is generating heat at an uniform rate of 0.45×108 W/m3 because of nuclear fission. Heat is transfer to pressurized cooling water at 300 0C and surface heat transfer coefficient is 4500 W/m2k. calculate the maximum temperature in the fuel rod in the system. What is the change in Tmax if the fuel element is encapsulated in a thin metal cladding of thickness 0.5 mm. Neglect thermal resistance of the cladding.
