Minimum baffle spacing recommended in a shell and tube heat exchanger is equal to _____________________?
Correct answer: A. 5 cms
- A. 5 cms
- B. 40% of the I.D. of the shell
- C. 25 cms
- D. I.D. of the shell
Explanation
Baffle spacing should not be reduced below about 5 cm, because closer spacing increases shell-side pressure drop and makes fabrication and cleaning difficult. In practice, the allowable spacing also depends on shell diameter.
