You can get to it through ITT Bell & Gossett website, click on "Online Calculators" scroll down and click on 'Flow / Head - Variable Speed Pumping Wizard" and try it out.
Start at 5 gpm at 10 ft of head and then look at what happens to flow at different speeds. Directly proportional.
Try 5000 gpm at 10, 100, or a 1000 ft of head.
I test small pumps and i test BIG pumps. I test them at different speeds.
