You want to transfer No. 3 fuel oil $\left(30^{\circ} \mathrm{API}\right)$ from a storage tank to a power plant at a rate of $2000 \mathrm{bbl} / \mathrm{day}$. The diameter of the pipeline is $1 \frac{1}{2} \mathrm{in}$. sch 40 , with a length of $1200 \mathrm{ft}$. The discharge of the line is $20 \mathrm{ft}$ higher than the suction end, and both ends are at $1 \mathrm{~atm}$ pressure. The inlet temperature of the oil is $60^{\circ} \mathrm{F}$, and the transfer pump is $60 %$ efficient. If the specific heat of the oil is $0.5 \mathrm{Btu} /\left(\mathrm{lb}_{\mathrm{m}}{ }^{\circ} \mathrm{F}\right)$ and the pipeline is perfectly insulated, determine

(a) The horsepower of the motor required to drive the pump

(b) The temperature of the oil leaving the pipeline
