Determining Pump Dead Head Pressure and Pump Curve

WebCause and Effects of Dead Head Pump. The occurrence of dead head in a pump could be due to a pipeline blockage or a closed discharge valve. When this happens, there is no exit path for water. Thus the same fluid volume continually circulates. As a result, the fluid temperature rises continually due to friction with the pump’s rotating impellers. Web16 sep. 2024 · Shaft Power Input. The pump power is supplied by an electric motor. The formula for calculating the output power of an electric driver is: P_S\ =\ 1.732\times V\ \times I\ \times PF\ \times Motor\ Efficiency\times Coupling\ Efficiency. V is the measured motor voltage in Volts, I is the measured motor current in Amperes, and PF is the power factor. hoppin john black eyed peas recipe
