Pumping power

Description

The power imparted into a fluid increases the energy of the fluid per unit volume. Thus the power relationship is between the conversion of the mechanical energy of the pump mechanism and the fluid elements within the pump. The pumping power depends on the change in total pressure between the inlet and outlet and the fluid flow-rate . The total pressure may have gravitational, static pressure and kinetic energy components.
