Minimum recommended baffle spacing in a shell and tube heat exchanger is about (where, D = shell diameter)?
Correct answer: A. 0.2 D
- A. 0.2 D
- B. 0.5 D
- C. 0.66 D
- D. 0.80 D
Explanation
Baffles should not be placed too close because this restricts shell-side flow and increases pressure drop; a usual minimum spacing is about one-fifth of the shell diameter. Hence the recommended value is 0.2D.
