The technique is to take several points on the original curve and apply thepump laws to determine the new head and flow at the new speed. The pump head versus flowrate curve that results from a change in pump speed is graphically illustrated in Figure 8.Figure 8 Changing Speeds for Centrifugal PumpRev. 0 Page 51 HT-03
