The unit of heat transfer co-efficient is_________________?
Correct answer: A. BTU/hr. ft2°F
- A. BTU/hr. ft2°F
- B. BTU/hr. °F. ft
- C. BTU/hr. °F
- D. BTU/hr. ft
Explanation
The heat-transfer coefficient relates heat flux to temperature difference, so its units are energy divided by time, area, and temperature difference: BTU/(hr·ft²·°F).
