The main purpose of providing fins on heat transfer surface is to increase the_________________?
Correct answer: C. Heat transfer area
- A. Temperature gradient
- B. Mechanical strength of the equipment
- C. Heat transfer area
- D. Heat transfer co-efficient
Explanation
Fins extend the available solid-fluid interface, increasing the heat-transfer area and therefore the total heat-transfer rate. They are used when increasing the coefficient directly is difficult or uneconomical.
