Water at 20°C is pumped at a rate of 15 L/s into a reservoir as shown in the Figure below. Between the pump and the reservoir is 150 m of 100 mm diameter PVC pipe, and the water surface elevation in the reservoir is 8 m above the centerline of the inflow pipe. The roughness height of the PVC pipe can be assumed to be negligibly small. Estimate the gauge pressure (kPa) on the downstream side of the pump. Pump 15 L/s-> P -150 m 100 mm Reservoir 8m

Question
Water at 20°C is pumped at a rate of 15 L/s into a reservoir as shown in the Figure
below. Between the pump and the reservoir is 150 m of 100 mm diameter PVC
pipe, and the water surface elevation in the reservoir is 8 m above the centerline of
the inflow pipe. The roughness height of the PVC pipe can be assumed to be
negligibly small. Estimate the gauge pressure (kPa) on the downstream side of the
pump.
