This is a heat transfer problem.

Question is the following;

You had been assigned, at General Motors, as design engineer to design a radiator ( Heat exchanger) for a new model car . It is necessary the the heat exchanger will be compact to fit within 2 feet by 3 feet space available in front of the car. IF the temperature of the incoming engine coolant is 150 degree Centigrade and outside temperature of air is about 38 C, what type of heat exchanger could reduce the temperature of the coolant to 40 C and find the surface area and number of the tubes necessary to do so. Select the Coolant properties as water. The coolant is circulated by water pump at rate of 0.5 kg/sec. Show all your work and justify the selection you made. Make all other engineering assumptions necessary for this design.

Dear student, kindly let me know in the comments if any portion is not readable or incomprehensible, I will try to explain it.

It is self evident that an air cooled heat exchanger needs to be used. Availability of more information can facilitate the further design parameters & the selection for this particular application.

You are working on a medical unit in an acute care hospital and had been assigned to care for M. Z., an 89-year old widow. She was admitted after experiencing a sudden onset R-sided weakness, followed by mental confusion and expressive aphasia. This combination of factors leads to problems with urinary continence. Foley catheter is placed to facilitate urinary drainage. Insertion of the catheter places M. Z. at risk for a urinary tract infection (UTI). What are the symptoms of...

if you transfer heat energy to a perfectly insulated cup of some liquid (no heat energy can be transferred in or out through the walls) what determines how much the temperature changes? Does it depend on how much heat energy you transfer, how much liquid there is in the cup, what the liquid is, or what the initial temerpature of the liquid is? Which of these factors do you think make a differnce in how much the temperture rises?
