A pump at a power plant supplies water to the boiler at a flow rate of 1,000 gal/min, measured at the pump inlet. Water enters the pump at 185 psig and 300 F. The pump discharge pressure is 2,985 psig. The isentropic efficiency of the pump is 70%. What is the required pump input power in HP? (Assume atmospheric pressure is 15 psia.) Answers:   2300 HP   1500 HP   1200 HP   2500 HP   1700 HP   2000 HP
