A closed-loop pump/pipe system has a head requirement of 35 m at a flow rate of 60 m3/h. The pump is a Bell & Gossett Series e-1531 Model 2AD operating at 3550 rpm with a 6-inch impeller.

a. Develop an equation for the system curve.

b. Use a computer program to develop an equation for the 6-inch impeller using data read from the pump performance curve.

c. Determine the capacity (m3/h) and head (m) 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 (kW) and efficiency of the pump.
