A plant piping system takes a process stream $\left(\mu=15 \mathrm{cP}, ho=0.9 \mathrm{~g} / \mathrm{cm}^{3}\right)$ from one vessel at $20 \mathrm{psig}$ and delivers it to another vessel at $80 \mathrm{psig}$. The system contains $900 \mathrm{ft}$ of $2 \mathrm{in}$. Sch. 40 pipe, 24 standard elbows, and 5 globe valves. If the downstream vessel is $10 \mathrm{ft}$ higher than the upstream vessel, what horsepower pump would be required to transport the fluid at a rate of $100 \mathrm{gpm}$, assuming a pump efficiency of $100 %$ ?
