Maximum water velocity in tubes of a 1-2 shell and tube heat exchanger may be around _____________ metres/second?
Correct answer: A. 1
- A. 1
- B. 10
- C. 20
- D. 30
Explanation
Tube-side water velocity is commonly kept near 1 m/s as an upper practical value in heat exchangers to limit erosion, vibration, and pressure drop. Values such as 10 m/s or more are far too high for this conventional design guideline.
