Which tube arrangement in a heat exchanger would facilitate highest heat transfer rate ?
Correct answer: A. Triangular pitch
- A. Triangular pitch
- B. Square pitch
- C. Diagonal square pitch
- D. Heat transfer rate is independent of tube arrangement
Explanation
Triangular pitch packs more tubes into a given shell area and produces stronger shell-side turbulence, giving a higher heat-transfer rate than square arrangements. Square pitch is preferred when easier mechanical cleaning is more important.
