In an extended surface heat exchanger, fluid having lower co-efficient________________?
Correct answer: B. Flows outside the tubes
- A. Flows through the tube
- B. Flows outside the tubes
- C. Can flow either inside or outside the tubes
- D. Should not be used as it gives very high pressure drop
Explanation
The lower heat-transfer coefficient produces the greater thermal resistance, so that fluid is placed outside the tubes where extended fins can increase the effective heat-transfer area. The higher-coefficient fluid is generally passed inside the tubes for easier cleaning and better heat transfer.
