A two-tank pump/pipe system has a head requirement of 23.4 ft at a flow rate of 100 gpm. The elevation difference between the fluid surfaces in the tanks is 10 ft. The pump is a Bell & Gossett Series e-80 Model 2.5x2.5x9C operating at 1170 rpm with a 7.5-inch impeller.

a. Develop an equation for the system curve.

b. Use a computer program to develop an equation for the 7.5-inch impeller using data read from the pump performance curve.

c. Determine the capacity (gpm) and head (ft) of the pump/pipe system by simultaneously solving the pump curve and system equations.

d. Use the pump performance curve to determine the power draw (hp) and efficiency of the pump.
