Baffles are provided in heat exchangers to increase the________________?
Correct answer: A. Heat transfer co-efficient
- A. Heat transfer co-efficient
- B. Heat transfer area
- C. Fouling factor
- D. Heat transfer rate
Explanation
Baffles redirect the shell-side fluid and increase turbulence, reducing the thermal boundary layer and raising the heat-transfer coefficient. They do not directly increase the exchanger's heat-transfer area.
