Inlet radius 300 mm, outer radius 150 mm, flow rate 0.05 m3/s, inlet guide blade 30 degree, angle the absolute velocity at exit makes an angle of 80 degree with the axis inlet absolute velocity 6 m/s, exit absolute velocity 3 m/s; overall efficiency 80%, hydraulic efficiency 90%. Determine head and power output if the angular velocity is 25 rad/s.
