Question
A scale model of a pump has been tested and the following results obtained.
Impeller diameter (D) 110mm
Power input (P) 2.5kW
Speed (N) 1500 r.p.m.
Flow (Q) 14.5 litres/sec
Head (H) 17m
Efficiency (E) 60%
You are to determine the speed and size of a geometrically similar pump which would deliver a flow rate of 25 litres/sec against a 22m resistance head. Determine the power input required by this pump.
