System Curve Meets Pump Curve: Static Head, k·Q² and the Operating Point
This lesson is part of the course
In this lesson
You tabulate the system curve and a fictional pump curve over a grid of flows, locate their crossing in the grid, calculate the exact operating point by formula and chart both curves.
