In a shell and tube heat exchanger, putting a longitudinal baffle across the shell, forces the shell side fluid to pass _____________ through the heat exchanger ?
Correct answer: B. Twice
- A. Once
- B. Twice
- C. Thrice
- D. Four times
Explanation
A longitudinal baffle divides the shell into two parallel flow passages, so the shell-side fluid travels through the exchanger twice before leaving. This is called a two-pass shell arrangement.
