Abstract:

Hydraulic nozzles are widely used in industry as well as human life. The hydraulic energy could be converted to mechanical energy (momentum force) by using a hydraulic nozzle. Due to nozzle resistance theflow energy is lost. Therefore, taking high efficency is necessary. This paper presents the equations to optimize hydraulic nozzle. The equations illustrate the pressure dropon nozzle and friction pressure loss along conduit and other equations for calculating pressure drop, friction loss relatively on an optimal nozzle. Based on those equations, author suggests the equations to determine the optimal diameter also pressure loss and velocity on an optimal nozzle. Further, author research the influence of fluid specific gravity, the flow rate and the head static on the optimal nozzle performance.
