A propeller turbine runner has OD of 4.5 m & the diameter of the hub 2 m.

It is required to develop 20600 KW when running at 150 rpm under a head of 21 m. Assuming hydraulic efficiency of 94% & overall efficiency of 88% determine the runner vane angles at inlet & exit at the mean diameter of the vanes. Also determine the runner vane angles at inlet & exit at two sections near the hub & outer Periphery.
