Centrifugal pumps power losses

ACTUAL PERFORMANCE OF CENTRIFUGAL PUMP. The developed head of an actual pump is considerably less than that calculated from the ideal pump relation of Eq. (8.21). Also, the efficiency is less than unity and the fluid horsepower is greater than the ideal horsepower. Head losses and power losses will be diseussed separately. [Pg.201]

For a forced vortex, the angular speed is constant and the liquid revolves as a solid body. Disregarding friction losses, Stepanoff (1993) claims that no power would be needed to maintain the vortex. The pressure distribution of this ideal solid body rotation is a parabolic function of the radius. When the forced vortex is superimposed on a radial outflow, the motion takes the form of a spiral. This is the type of flow encountered in a centrifugal pump. Particles at the periphery are said to carry the total amount of energy applied to the liquid. [Pg.424]
