The fluid enters the blades in the radial direction, i.e. at an angle of α₁ = 0°, and exits the blades at an angle of 35° from the radial direction. i.e. α₂ = 35⁰. The inlet radius and blade width are r₁ 12.0 cm and b₁ = 18.0 cm, respectively. The outlet radius and blade width are 1₂ = 24.0 cm and b₂ = 16.2 cm, respectively. Assuming 100 percent efficiency, and if the volumetric flow-rate through the pump is 0.573 m³/s, compute the net head produced by the centrifugal pump. Furthermore, calculate the required brake horsepower in Watts.
