Now let’s put all four curves on a single chart. Here it will give you an overall pump performance review. You can see how these curves interact with each other. As said earlier, all these curves are interrelated and provide valuable information about the centrifugal pump's performance.
The first curve under pump performance characteristic is the head Vs. flow rate curve. It is also known as a pressure vs. quantity curve. To draw this curve head is plotted on Y-axis, and the flow is plotted on X-axis. You can see the sample HQ curve in the image here. Now let’s convert this curve to a word so that
