Design system 2

Design system
Solve the problem of fluid flow through the heat exchanger. Give flow rate as an input and for the flow rate calculate how much head loss will occur.
So in your program, you should be able to input the desired “flow rate” and then write a code to calculate head loss.
Make sure to show a block diagram with clear equations and step you are using.
Question is the following
If you are to flow a fluid through the heat exchanger with the desired flow rate (e.g. 10 gallons/hr) then what will be the head loss in you heat exchanger.
