Water at $160^{\circ} \mathrm{F}$ is to be pumped at a rate of $100 \mathrm{gpm}$ through a 2 in. sch 80 steel pipe from one tank to another located $100 \mathrm{ft}$ directly above the first. The pressure in the lower tank is $1 \mathrm{~atm}$. If the pump to be used has a required NPSH of $6 \mathrm{ft}$ of head, what is the maximum distance above the lower tank that the pump may be located?
