Discussion Forum : Heat Transfer, Refrigeration and Air Conditioning - Section 4 (Q.No. 38)
38.
A designer chooses the values of fluid flow rates and specific heats in such a manner that the heat capacities of the two fluids are equal. A hot fluid enters the counter flow heat exchanger at 100° C and leaves at 60° C. A cold fluid enters the heat exchanger at 40° C. The mean temperature difference between the two fluids is

The mean temperature for hot fluid = (hot fluid inlet T+hot fluid exit T)/2.

tm = mean temperature difference between the two fluids for counter flow heat exchanger,
tm = th1-tc2 = th2-tc1.
tm = th2-tc1 = 60-40 = 20.
tm = th1-tc2 = th2-tc1.
tm = th2-tc1 = 60-40 = 20.
