A centrifugal impeller is a rotating component used in pumps, compressors, and turbines to transfer energy from the motor to the fluid. It works by converting rotational kinetic energy into hydrodynamic energy, increasing the fluid's velocity and pressure as it moves outward from the center (or eye) of the impeller to the outer periphery.

Key Features of a Centrifugal Impeller:
Design: Typically consists of a series of backward or forward-curved blades mounted on a central hub.
Function: As the impeller spins, fluid enters axially at the center, gains velocity due to the blades, and is then directed radially outward.
Applications: Used in centrifugal pumps, gas compressors, and turbochargers.

Working Principle:
1. Fluid enters the impeller near the center (eye).
2. The impeller blades impart kinetic energy to the fluid.
3. The fluid accelerates outward along the blades.
4. The high-velocity fluid moves into the diffuser or volute, where kinetic energy is converted into pressure energy.

Advantages:
High efficiency in fluid transportation.
Suitable for handling large volumes of liquids or gases.
Compact design suitable for various industrial applications.
