WebbFluid entering a centrifugal pump is immediately directed to the low pressure area at the center or eye of the impeller. As the impeller and blading rotate, they transfer momentum to incoming fluid. A transfer of momentum to the moving fluid increases the fluid's velocity. As the fluid's velocity increases its kinetic energy increases. Webbx is independent of the distance from the inlet, and the velocity proflle will appear the same for all values of x. Since @v x=@z= 0 (assumption 3), it follows that v x= v x(y) is a function of yonly.
