In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement ?
Correct answer: A. Results in higher shell side pressure drop
- A. Results in higher shell side pressure drop
- B. Can accomodate less number of tubes for a given shell diameter
- C. Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell
- D. side fluid
- E. Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer
- F. co-efficient
Explanation
Triangular pitch places tubes closer together and forces the shell-side fluid through more tortuous passages, giving higher turbulence and heat transfer but also a higher pressure drop. Square pitch is preferred when mechanical shell-side cleaning is required.
