8-91E Steam is to be condensed on the shell side of a heat exchanger at 120°F. Cooling water enters the tubes at 60°F at a rate of 115.3 lbm/s and leaves at 73°F. 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 = 77°F. | |
