In case of a multipass shell and tube heat exchanger, providing a baffle on the shell side ______________ the heat transfer rate?
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Does not affect
- D. May increase or decrease, depends on the type of baffle
Explanation
Shell-side baffles force the fluid across the tubes instead of allowing it to flow mainly parallel to them. This increases turbulence and velocity, thereby increasing the heat-transfer rate.
