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.
WebThe System Curve. A fluid flow system is characterized with the System Curve - a graphical presentation of the Energy Equation. The system head visualized in the System Curve above is a function of elevation - or the static head and the major and minor losses in the system and can be expressed as: h = dh + hl (1) where. h = system head (m) cityhouseing.co.krWebSchool Information. 7801 Glenarden Parkway.
