Example1: Pipes & Pumps Given: A pump station (B) moves water from a lower reservoir (A) to a distant reservoir (C) at a higher elevation, as shown in the figure below. The pump curve is also provided below and the equation for the pump curve is Head (ft) = 250 - 0.0025 *Q(gpm)2.5. The pump inlet and outlet are at the same elevation. Find: a) What flow rate (gpm) can be maintained from the lower reservoir to the upper reservoir using a single pump B? b) What flow rate can be maintained using 2 pumps in series at B? c) What flow rate can be maintained using 2 pumps in parallel at B? d) What is the pressure (psi) at the pump inlet? Solution: Total Length A-B = 4000' @ 3" dia Total Length B-C = 12000' @ 6" dia C = 120 255' 205' 65' 190' C 45' 40' A B
