Please answer 5 out of the following 7 questons within 10 minutes after the start of the quiz. Why would you want to maximize the length of tubing you could pack into a heat exchanger? How does the energy of a flowing fluid differ from that of a stationary fluid? Define all terms describing the energy of each. Ex. Score: 0 of 1 pt
Solution
>> Solution 1.
We do want to maximize the length of tubing because more the length of tube, more the distance fluid travelled to exchange heat, more the time available for heat exhanging, more efficiency of heat exchanger....
>> Solution 2.
Stationary fluid have Pressure energy and Potential Energy
Pressure Energy in Stationary fluids = Force Acting/Cross Sectional Area
and, Potential Energy head = Height from reference at which fluid is kept
>> Flowing fluid in addition to Pressure Energy & Potential Energy also have Kinetic Energy
and, Kinetic Energy = (1/2)m*v2
