Hydraulic energy balance is held in radial direction at trailing edge of impeller outlet in pump and at leading edge of impeller inlet in water turbine. Hydraulic energy output at trailing edge of impeller outlet in pump and hydraulic energy input at leading edge of impeller inlet in water turbine appear in the form of product of fluid particle’s rotational and tangential movement. The rate of hydraulic energy head H and flow rate Q is equivalent to the rate of centrifugal and tangential forces, hence equivalent to rate of rotational and tangential distances of which fluid particle had moved at those sections.
