Oil is being pumped from a large storage tank, where the temperature is $70^{\circ} \mathrm{F}$, through a 6 in. ID pipeline. The oil level in the tank is $30 \mathrm{ft}$ above the pipe exit. If a $25 \mathrm{hp}$ pump is required to pump the oil at a rate of $600 \mathrm{gpm}$ through the pipeline, what would the temperature of the oil at the exit be, if no heat is transferred across the pipe wall? State any assumptions that you make. Oil properties: $\mathrm{SG}=0.92, \mu=35 \mathrm{cp}, c_{p}=0.5 \mathrm{Btu} /\left(\mathrm{lb}_{\mathrm{m}}{ }^{\circ} \mathrm{F}\right)$.
