Which of the following is the most common type of baffle used in industrial shell and tube heat exchanger ?
Correct answer: B. 25% cut segmental baffle
- A. 75% cut segmental baffle
- B. 25% cut segmental baffle
- C. Orifice baffle
- D. Disk and doughnut baffle
Explanation
The 25% cut segmental baffle is the usual industrial choice because it provides effective cross-flow over the tubes without imposing excessive pressure drop. Larger cuts give weaker cross-flow, while special baffles are less common.
