Web9.2. Calculations. If the volumetric measuring tank was used, then calculate the flow rate from: Correct the pressure rise measurement (outlet pressure) across the pump by adding a 0.07 bar to allow for the difference of 0.714 m in height between the measurement point for the pump outlet pressure and the actual pump outlet connection. WebDec 13, 2024 · The result of zero pump head is that the pump’s energy can be entirely applied to moving water, rather than lifting it, so flow is faster. As pump head increases, …

WebIn 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). WebJun 8, 2024 · So, when pressure in the pump causes more load on the motor, it slows down. When the motor slows down, the flow rate drops at the same percentage. A motor that operates at about 2000 RPM at low pressures will typically slow down to about 1750 RPM when the pump is pressurized to the maximum rating. It stands to reason, then, that …
