Performance Curve
The performance curve graph displays the relationship between Head (in meters) and Flow Rate (in Liters per minute) for the GMD-20R pump model. It shows multiple curves, indicating different operational points.
X-axis: Flow Rate (Q) in L/min, ranging from 0 to 32.
Y-axis: Head (H) in meters, ranging from 0 to 7.
The curves are labeled '20R' and show decreasing head as flow rate increases.
