In a shell and tube heat exchanger, floating head is used for _________________?
Correct answer: B. Large temperature differentials
- A. High heat transfer co-efficient
- B. Large temperature differentials
- C. Low pressure drop
- D. Less corrosion of tubes
Explanation
A floating head allows one tube sheet to move relative to the shell, accommodating differential thermal expansion. This is especially important when the shell and tubes experience large temperature differences.
