A two stage centrifugal pump is designed to discharge water at a total head of 70 m with an overall efficiency of 0.76. The pump runs at 2331.6 rpm. The actual head developed (per stage) is 65% of the theoretical head. The flow at the inlet is pure radial. The impeller at the exit has a diameter of D₂ = 0.219 m and a width of by 0.0216 m. The outlet blade angle is

Question
A two stage centrifugal pump is designed to discharge water at a total head of 70 m with an overall efficiency of 0.76. The pump runs at 2331.6 rpm. The actual head developed (per stage) is 65% of the theoretical head. The flow at the inlet is pure radial. The impeller at the exit has a diameter of D₂ = 0.219 m and a width of by 0.0216 m. The outlet blade angle is B₂ = 28.
