A high pressure pump takes water in at 708F, 1 atm, through a 1 in. ID suction line and discharges it at 1000 psig through a 1/8 in. ID line. The pump is driven by a 20 hp motor and is 65% efficient. If the flow rate is 500 g/s and the temperature of the discharge is 738F, how much heat is transferred between the pump casing and the water, per pound of water? Does the heat go into or out of the water?
