Calculate the rate of irreversibility for the heat exchanger in Problem 52 and an ambient temperature of 298 K.
Problem
An insulated heat exchanger is proposed to be used to cool hot air with a flow of cool water. The air enters at 200 kPa and 100°C, and exits at 195 kPa and 0°C. The mass flow rate of the air is 2.0 kg/s. The water enters the heat exchanger at 30°C and exits at 95°C. Calculate the entropy generation rate of the proposed heat exchanger. Is this heat exchange process possible?
