A Francis turbine develops 500 kW at 500 rpm under a head of 50 m. The hydraulic efficiency is 95% and the overall efficiency is 85%. The flow ratio is 0.20cand the ratio of width to diameter is 0.15. The blades occupy 5% of the outlet area and the inside diameter is half of the outside diameter. Find the guide blade angle at inlet, blade angles at inlet and outlet. The velocity of flow at inlet and outlet are equal.
