Extremely large or small volumes of fluids are generally best routed through the shell side of a shell and tube heat exchanger, because of the________________?
Correct answer: B. Flexibility possible in the baffle arrangement
- A. Less corrosion problems
- B. Flexibility possible in the baffle arrangement
- C. Low pressure drop
- D. High heat transfer co-efficient
Explanation
The shell side can handle widely varying fluid volumes because baffle spacing and arrangement can be changed to adjust the flow area and velocity. This flexibility is the key advantage listed, rather than inherently low pressure drop or higher heat-transfer coefficient.
