Question
A centrifugal pump rotates at 900 rpm. The
following data are taken: r, = 2", r, = 8", the area
at the inlet to the impeller region is A, - 12-rt
in', and the outer area of the impeller region is
A, = 30-rt in", B, = 135°, B,= 120°, radial flow
at entrance to blades. Neglecting friction,
calculate the velocities at entrance and exist
and the power transmitted to the water?
