Centrifugal Pump

A centrifugal pump is a mechanical device that uses centrifugal force to transport fluids by converting mechanical energy into hydraulic energy. It consists of a rotating impeller that accelerates the fluid and a stationary casing that converts the kinetic energy into pressure energy.

Inward Radial Flow Reaction Turbine

An inward radial flow reaction turbine is a type of hydraulic turbine that converts hydraulic energy into mechanical energy. It operates by admitting water at the center of the turbine wheel and allowing it to flow outwards radially. As the water flows through the turbine blades, it exerts a reaction force on the blades, causing the turbine wheel to rotate.

Reverse Operation

The reverse operation of a turbine is a pump. In the case of an inward radial flow reaction turbine, the reverse operation would be an inward radial flow reaction pump, which is essentially a centrifugal pump.

Explanation

- When a fluid flows through a centrifugal pump, it enters the pump at the center of the impeller and is accelerated by the rotating blades.
- The centrifugal force generated by the impeller pushes the fluid towards the outer edges of the impeller, creating a pressure difference.
- This pressure difference causes the fluid to be pushed towards the outlet of the pump, where it exits at a higher pressure than the inlet.
- In the case of an inward radial flow reaction turbine, the fluid enters the turbine at the outer edges of the turbine wheel and flows inwards towards the center.
- As the fluid flows through the turbine blades, it exerts a reaction force on the blades, causing the turbine wheel to rotate and convert hydraulic energy into mechanical energy.
- In the reverse operation, a centrifugal pump would act as an inward radial flow reaction pump, where the fluid enters at the center of the impeller and flows outwards towards the outer edges.
- The impeller of the pump would rotate in the opposite direction compared to the turbine, but the overall principle of fluid acceleration and pressure generation remains the same.
- Therefore, a centrifugal pump acts as a reverse of an inward radial flow reaction turbine.

Overall, a centrifugal pump can be considered as the reverse of an inward radial flow reaction turbine because they both involve fluid flow and pressure generation, but in opposite directions.
