QUESTION:

A pump is installed to deliver water from a reservoir of surface elevation zero to another reservoir of elevation on 290. The 10-in-diameter suction pipe (f = 0 022) is 90 ft long, and the 8-in-diameter discharge pipe If = 0.028) is 4900 ft long.

Minor losses are neglected.

The pump character is c at 1100 rpm is defined by:

h_a = 365 - 20Q² (1)

where ha, the pump head, is in feet (ft) and Q, volumetric flowrate, in cubic feet per second (ft3/s).
