The ratio of velocity head to tube side return loss in case of a multipass shell and tube heat exchanger is ________________?
Correct answer: D. 1/4
- A. 2
- B. 1/2
- C. 4
- D. 1/4
Explanation
In a multipass shell-and-tube exchanger, the tube-side return loss is commonly taken as four velocity heads. Hence, velocity head divided by return loss is 1/4.
