Question
A pumping system is required that will deliver at least 50,000 GPM against a head of 100 ft is needed for
a water ride. The system schematic is given below. Note that the loss coefficient for the pumps
accounts for the losses in piping connecting multiple pumps. Use Gould pumps to satisfy this
requirement. Submit your loss curve superimposed on the pump curves for the selected pumps in your
Excel file. Determine the following.
a. The pumps (all the same) to satisfy this requirement.
b. The operating point of these pumps.
