A $60 %$ efficient pump driven by a $10 \mathrm{hp}$ motor is used to transfer bunker $\mathrm{C}$ fuel oil from a storage tank to a boiler through a well-insulated line. The pressure in the tank is $1 \mathrm{~atm}$, and the temperature is $100^{\circ} \mathrm{F}$. The pressure at the burner in the boiler is $100 \mathrm{psig}$, and it is $100 \mathrm{ft}$ above the level in the tank. If the temperature of the oil entering the burner is $102^{\circ} \mathrm{F}$, what is the oil flow rate, in gpm? (Oil properties: $\mathrm{SG}=0.8, c_{p}=0.5 \mathrm{Btu} /\left(\mathrm{lb}_{\mathrm{m}}{ }^{\circ} \mathrm{F}\right)$ )
