Hot exhaust gases leaving an internal combustion engine at 400 C and 150kPa at a rate of 0.8 kg/s is to be used to produce saturated steam at 200 C in an insulated heat exchanger. Water enters the heat exchanger at the ambient temperature of 20 C, and the exhaust gases leave the heat exchanger at 30 C. Determine (a) the rate of the steam production, (b) the rate exergy destruction in the heat exchanger, and (c) the second-law efficiency of the heat exchanger.
