Venturi effect - Wikipedia, the free encyclopedia
A venturi can be used to measure the volumetric flow rate Q. . connected to a system consisting of a venturi to increase the liquid speed (the . See aspirator and pressure head for discussion of this type of siphon.
NPSH - Wikipedia, the free encyclopedia
NPSH is an initialism for Net Positive Suction Head. . effect will be cavitation: vapor bubbles may reduce or stop the liquid flow, as well as damage the system. . Additionally, the inevitable increase in vibration can cause other mechanical .
Irrigation Water Pumps
However, the flow rate and total dynamic head will be determined by the type of irrigation system, . The velocity of the water has a significant effect on friction loss. . The NPSH curve will increase with increasing flow rate through the pump.
