Akaplan turbine operating under a net head of 20m develops 16000kw with an overall efficiency of 80 per cent. the diameter of the runner is 4.2 m while the hub diameter is 2m and the dimensionless power specific speed is 3 rad. if the hydraulic efficiency is 90 per cent, calculate the inlet and exit angles of the runner blades at the tip and at the hub if the flow leaving the runner is purely axial.
