MCQOPTIONS

1.	In a Counter flow heat exchanger design, fluid rates and specific heats were chosen in such a manner that heat capacities of both the fluids are same. A hot fluid enters at 100°C and leaves at 60°C. The cold fluid enters heat exchanger at 40°C. The mean temperature difference between the two fluids is
A.	40°C
B.	60°C
C.	20°C
D.	36.6°C
Answer» D. 36.6°C
