discharge pressure centrifugal pump Pump engineering

2018-9-21  Assuming velocity in the discharge line to the first tank (vessel 1) is low, as a first approximation, discharge pressure will be approx 72cm of water column, let say it is 75cmH2O. This converts to a discharge press of (0.75/10.2)*14.51 = 1.07psig, since 10.2m H20 = 14.51psi. RE: discharge pressure centrifugal pump.

What is Centrifugal Pump Definition

2019-5-22  The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, slowing down the fluid’s rate of flow. Therefore, according to Bernoulli’s principle, the volute converts kinetic energy into pressure by reducing speed while increasing pressure. Some centrifugal pumps contain diffusers.
