A Goulds 4x6-13 pump has NPSHR=2.45E-6(GPM^2)+0.00511GPM +2.13 is used to pump water at 140 F from a reservoir open to the atmosphere(Patm=14.7 psia) at a rate of 750 gpm. Total

minor loss coefficient for the inlet is C=50 FT. The pipe is commercial steel and is 4 inches inside diameter.What is the maximum horizontal distance away from the source reservoir (in feet) that the pump can be located to avoid cavitation?
