Baffles in the shell side of a shell and tube heat exchanger ?
Correct answer: B. Increase the shell side heat transfer co-efficient
- A. Increase the cross-section of the shell side liquid
- B. Increase the shell side heat transfer co-efficient
- C. Force the liquid to flow parallel to the bank
- D. Decrease the shell side heat transfer co-efficient
Explanation
Baffles redirect shell-side fluid across the tube bundle rather than allowing mainly parallel flow, increasing turbulence and the effective heat-transfer coefficient. They also support the tubes and reduce vibration.
