A 60% efficient pump driven by a 10 hp motor is used to transfer bunker C fuel oil from a storage tank to a boiler through a well-insulated line. The pressure in the tank is 1 atm, and the temperature is 1008F. The pressure at the burner in the boiler is 100 psig, and it is 100 ft above the level in the tank. If the temperature of the oil entering the burner is 1028F, what is the oil flow rate, in gpm? [Oil properties: SG ¼ 0.8, cp ¼ 0:5 Btu/(lbm 8F).]
