Shell side heat transfer co-efficient in case of square pitch as compared to the triangular pitch under similar condition of fluid flow and tube size is_____________?
Correct answer: D. Less
- A. More
- B. Same
- C. Twice
- D. Less
Explanation
Triangular pitch gives greater shell-side turbulence and a larger heat-transfer coefficient than square pitch under comparable conditions. Therefore, square pitch has the lower coefficient.
