3.2 Pump characteristics - TU Delft OCW
o Net Positive Suction Head (NPSH) curve. Each of the characteristics is explained in the next sections for propeller pumps. 3.2.1 Q-H curve The Q-H curve is the relation between the volume flow and the pressure at a constant speed of the pump crank. The H in the curve is the difference in energy level between the suction and the pressure side ...
