$14-56$E A centrifugal pump is used to pump water at $77\backslash$deg Ffrom a reservoir whose surface is $20\mathrm{.}0$ft above the centerlineof the pump inlet $($Fig$.$ P$14-56$E$).$ The piping system consistsof $67\mathrm{.}5$ft of PVC pipe with an ID of $1\mathrm{.}2$ in and negligibleaverage inner roughness height. The length of pipe from thebottom of the lower reservoir to the pump inlet is $12\mathrm{.}0$ft$.$There are several minor losses in the piping system: a sharp$-$edged inlet $($K$\_($L$)=0\mathrm{.}5),$ two flanged smooth $90\backslash$deg regularelbows $($ K$\_($L$)=0\mathrm{.}3$ each$),$ two fully open flanged globe valves each, PLEASE USE volume flow rate $=40$ gallon$/$minute and thanks in advance
