In a system where there is flow, the total head is the difference between the discharge head and the suction head plus the friction head and this sum will be less than the shut-off head. The plot of head versus flow rate is known as the pump's performance curve (see Figure 7 for an example of a pump performance curve).

Osborne Reynolds (1842–1912) experimentally investigated the relationship between the pressure drop and flow rate in a pipe. He found that at low rates, the pressure drop was directly proportional to the flow rate. He also observed that as he increased the flow rate, the measured data started to behave erratically.

of the speed of flow determined by a pressure measurement, together with the known areas of the tube and the constriction, suffices to determine the rate of flow of fluid through the tube. Although we have derived the relationship between pressure and velocity for a Venturi tube, the same relationship is true for any case of.

the fluid. If the friction losses in the inlet and outlet tubes can be neglected, the head produced by the pump is equal to h, the height of the free end of the hose above the free surface of the supply reservoir. Each pump has a characteristic relationship between head and flow rate. • An increase in head causes a decrease in Q.
