Parallel straight line pattern of temperature distribution for both hot and cold fluids is observed in case of heat exchanger of the type________________?
Correct answer: C. Counter flow with equal heat capacities
- A. Parallel flow with equal heat capacities
- B. Counter flow with unequal heat capacities
- C. Counter flow with equal heat capacities
- D. Parallel flow with unequal heat capacities
Explanation
For counterflow with equal heat-capacity rates, both temperature profiles have the same slope, so they appear as parallel straight lines with a constant temperature difference. Unequal heat capacities give different slopes, while parallel flow does not produce this pattern.
