In most of the shell and tube heat exchangers, the tube pitch is generally ______________ the tube diameter?
Correct answer: A. 1.25-1.50 times
- A. 1.25-1.50 times
- B. Less than
- C. 2.5 times
- D. one-fourth of
Explanation
Tube pitch is commonly about 1.25 to 1.5 times the tube outside diameter, providing space for shell-side flow, fabrication, and tube cleaning. A smaller pitch would leave inadequate clearance between adjacent tubes.
