An organic fluid is to be pumped at a rate of $300 \mathrm{gpm}$, from a distillation column reboiler to a storage tank. The liquid in the reboiler is $3 \mathrm{ft}$ above ground level, the storage tank is $20 \mathrm{ft}$ above ground, and the pump will be at ground level. The piping system contains 14 std elbows, 4 gate valves, and $500 \mathrm{ft}$ of $3 \mathrm{in}$. sch 40 pipe. The liquid has an $\mathrm{SG}$ of 0.85 , a viscosity of $8 \mathrm{cP}$, and a vapor pressure of $600 \mathrm{mmHg}$. If the pump to be used has characteristics similar to those given in Appendix $\mathrm{H}$, and the pressure in the reboiler is $5 \mathrm{psig}$, determine

(a) The motor speed to be used

(b) The impeller diameter

(c) The motor horsepower and required torque

(d) Where the pump must be located to prevent cavitation
