Question:

A 6 in. Sch. 40 pipeline carries an intermediate product stream $(\mu=15 \mathrm{cP}, \mathrm{SG}=0.85)$ at a velocity of $7.5 \mathrm{ft} / \mathrm{s}$ from a storage tank at $1 \mathrm{~atm}$ pressure to a plant site. The line contains $1500 \mathrm{ft}$ of straight pipe, $2590^{\circ}$ elbows, and 4 open globe valves. The liquid level in the storage tank is $15 \mathrm{ft}$ above ground level, and the pipeline discharges into a vessel that is $10 \mathrm{ft}$ above ground at a pressure of $10 \mathrm{psig}$. What is the required flow capacity in gpm and the pressure head to be specified for the pump needed for this job? If the pump is $65 %$ efficient, what horsepower motor is required to drive the pump?
