Number 3 fuel oil $left(30^{circ} mathrm{API} ight)$ is transferred from a storage tank at $60^{circ} mathrm{F}$ to

Number 3 fuel oil $\left(30^{\circ} \mathrm{API}\right)$ is transferred from a storage tank at $60^{\circ} \mathrm{F}$ to a feed tank in a power plant at a rate of $2000 \mathrm{bbl} / \mathrm{day}$. Both tanks are open to the atmosphere and are connected by a pipeline containing $1200 \mathrm{ft}$ equivalent length of $1 \frac{1}{2} \mathrm{in}$. sch 40 steel pipe and fittings. The level in the feed tank is $20 \mathrm{ft}$ higher than that in the storage tank, and the transfer pump is $60 %$ efficient. The Fanning friction factor is given by

\[f=\frac{0.0791}{N_{R e}^{1 / 4}} \text {. }\]

(a) What horsepower motor is required to drive the pump?

(b) If the specific heat of the oil is $0.5 \mathrm{Btu} /\left(\mathrm{lb}_{\mathrm{m}}{ }^{\circ} \mathrm{F}\right)$ and the pump and transfer line are perfectly insulated, what is the temperature of the oil entering the feed tank?
