The head and flow rate determine the performance of a pump, which is graphically shown in the figure as the performance curve or pump characteristic curve. The main reason for using head instead of pressure to determine the performance of a centrifugal pump is that the height of the fluid column is not dependent on the specific gravity weight of the liquid , while the pressure from a pump
Assessing Flow Rate in a Functioning System. Let's say, for example, that you need to move 200 litres of a fluid every 20 minutes. That means your equipment, have to be able to produce a flow rate of 20 litres per minute, or 3.33 litres per second.
