WebSep 9, 2024 · The maximum allowable speed is also typically shown on the pump curves chart, since most pumps can’t run at what the top motor speed is. Flow. The flow (#3 on pump curve chart, measured in GPM/Liters Per Minute) is determined by pump speed (RPM). Once the pump speed information is known you can determine the flow on the … WebPump design can also affect what the pump performance curve will look like. There are both flat and steep pump curves. Flat curves occur when there is a small change in head resulting in a big change in flow, as you can see here. Steep curves, on the other hand, occur when there is both a small change in head and the flow, as shown here. WebSep 13, 2024 · THE FORMULA FOR PSI: FEET OF HEAD/2.31 = PSI.
