Q5.A centrifugal pump rotates at \( 1170 \mathrm{rpm} \). The pump operates at the design condition. The water exits the pump impeller at an angle of 30 o from the radial direction. The inlet radius of the pump impeller is \( 12 \mathrm{~cm} \), the blade width is \( 18 \mathrm{~cm} \), the outlet radius is \( 24 \mathrm{~cm} \), and the blade width is \( 14 \mathrm{~cm} \). The volumetric flow rate of the pump is \( 0.57 \mathrm{~m} 3 / \mathrm{s} \). a) Draw the blade inlet and outlet velocity triangles. b) Find the blade inclination angles, \( \beta \). c) Calculate the net head produced by the pump, and the power of the pump.
