Question
Performance data for a pump are listed in the following table.
Hp (ft) 179 176 165 145 119 84 43
Q (gpm) 0 500 1000 1500 2000 2500 3000
(a) Plot the system curve for the pump to move water between two open reservoirs,
through 2000 ft of 12 in. inner diameter commercial steel pipe containing 5 standard 90°
elbows and 2 open gate valves, if the elevation increase is 50 ft. Explain how plot was made.
(b) Determine the operating point, i.e., the volumetric flowrate in gpm and pump head
in ft.
(c) Calculate the power input (horsepower) to the pump at the operating point,
assuming its efficiency is 80%.
