Steam is to be condensed on the shell side of a heat exchanger at 120°F. Cooling water enters the tubes at 65°F at a rate of 108.6 lbm/s and leaves at 80°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 = 98°F

PLEASE EXPLAIN CLEARLY, WRITE CLEARLY, DOUBLE CHECK ANSWERS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
