Where is the impeller?

The impeller is typically found within a pump or a turbine, where it serves to move fluids by converting rotational energy into hydrodynamic energy. In a centrifugal pump, for example, the impeller is located inside the pump casing and spins to push the fluid outwards, creating flow. In a turbine, the impeller is part of the rotor assembly that harnesses fluid energy to produce mechanical power. Its placement and design are crucial for the efficiency and performance of the system it operates in.
