Question #59888

A pump is installed to deliver water from a reservoir of surface elevation zero to another reservoir of elevation 290 ft. The 10-in-diameter suction pipe (f = 0.022) is 90 ft long, and the 8-in-diameter discharge pipe (f = 0.028) is 4900 ft long. Minor losses are neglected.

The pump characteristic at 1100 rpm is defined by:

ha = 365 – 20 Q2 (1)

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

1. Compute graphically the flowrate and the pump head at the operation conditions.

2. Repeat the question for the case of two identical pumps in series

3. Repeat the question for the case of two identical pumps in parallel
