A pump operating at steady state takes in saturated liquid water at 65 lbf/in.2 at a rate of 10 lb/s and discharges water at 1000 lbf/in.2 The isentropic pump efficiency is 80.22%. Heat transfer with the surroundings and the effects of motion and gravity can be neglected. If T0 5 75°F, determine for the pump

(a) the exergy destruction rate, in Btu/s.
