Pump Curve vs System Curve - Example Problem

Step by step walkthrough of How to Find the System Curve for Pump Head using the Energy Equation, and how to use pump curves to find the system's flowrate with the given pump.

These plots do go by slightly different names, pump curves, pump performance curves, pump characteristics curves. This Pump Curve Example Problem shows how to read pump curves and how to plot the system curve for use in pump selection.

You will usually need to use the Darcy Weisbach Equation along with the Moody Diagram, and also tables for looking up Minor Losses Coefficients.
