1. Consider the parallel flow heat exchanger of Prob. 4.86. Verify that the stream of air exits at 780°R and the stream of carbon dioxide exits at 760°R. Pressure is constant for each stream. For the heat exchanger, determine the rate of exergy destruction, in Btu/s. Let T0 5 537°R, p0 5 1 atm.

2. Air at T1 5 1300°R, p1 5 16 lbf/in.2 enters a counterflow heat exchanger operating at steady state and exits at p2 5 in lb/s, and (b) the rate of exergy destruction within the heat exchanger, in Btu/s. Ignore the effects of motion and gravity and let T0 5 60°F, p0 5 1 atm.
