Appendix G – Problem 25

G.25 Compute the weight moment of inertia (WR²) of a pump with a rated flowrate of 2935 m³/h, a rated pressure head of 100m, a rated speed of 1800 rpm, with a best efficiency of 80%. Use the graphs plotted based on the empirical relationships for weight moment of inertia shown in Figures 7.9. Note, the pump brake power used in Figures 7.9 – 7.11 is expressed in kW.
