A centrifugal pump rotates at n = 750 rpm. Water enters the impeller normal to the blades

Question:

A centrifugal pump rotates at ṅ = 750 rpm. Water enters the impeller normal to the blades (α₁ = 0°) and exits at an angle of 35° from radial (α₂ = 35°). The inlet radius is r₁ = 12.0 cm, at which the blade width b₁ = 18.0 cm. The outlet radius is r₂ = 24.0 cm, at which the blade width b₂ = 16.2 cm. The volume flow rate is 0.573 m³/s. Assuming 100 percent efficiency, calculate the net head produced by this pump in cm of water column height. Also calculate the required brake horsepower in W.
