💡 Centrifugal Pump Operation:
The centrifugal pump acts as a reverse of an inward radial flow reaction turbine. This means that the flow in centrifugal pumps is in the radial outward direction.
The centrifugal pump works on the principle of forced vortex flow, which means that when a certain mass of liquid is rotated by an external torque, the rise in pressure head of the rotating liquid takes place.
In a centrifugal pump casing, the flow of water leaving the impeller is a free vortex.
