Steam is to be condensed on the shell side of a heat exchanger at 50°C. Cooling water enters the tubes at 15°C at a rate of 55 kg/s and leaves at 23°C. Assuming the heat exchanger to be well insulated, determine (a) the rate of heat transfer in the heat exchanger and (b) the rate of exergy destruction in the heat exchanger. Take T0 = 25°C. |
