Recall that the maximum heat transfer possible is the product of the minimum heat capacity (mass flow rate times specific heat) times the difference between the hot and cold side inlet temperatures. Address the following questions related to heat exchanger effectiveness. a. Sketch the temperature profiles for a 50% and 80% effectiveness heat exchanger. (As with Problem 1, make sure you have the correct shape, which, including degree of steepness at each end). b. What is the effectiveness for a heat exchanger with the following characteristics: the hot side is water entering at 160 F and 2lb/s, and the cold side is air entering at 20 F and 4 lb/s. The HX has been designed to the correct shape, which, including degree of steepness at each end). b. achieve an air outlet of 110 F.
