It is not desirable to design a heat exchanger for LMTD correction factor, FT, of less than _________________?
Correct answer: C. 0.80
- A. 0.99
- B. 0.95
- C. 0.80
- D. 0.55
Explanation
A correction factor below about 0.80 indicates an inefficient exchanger arrangement and a rapidly declining temperature-driving force. Heat exchangers are therefore normally designed with FT at least 0.80.
