WebEquation 3-19 can be used to calculate the net positive suction head available for a pump. The units of NPSH are feet of water. NPSH = P suction − P saturation (3-19) where: By maintaining the available NPSH at a level greater than the NPSH required by the pump manufacturer, cavitation can be avoided. WebMay 13, 2024 · This is the equation for the velocity at any time during the coasting ascent. At the top of the trajectory, the velocity is zero. We can solve the velocity equation to determine the time when this occurs: Vo/Vt = tan (g * t (v=o) / …
