Question: A Francis Turbine with an overall efficiency of 75%is required to produce150 kW when working under a head of 7.62m.. Its peripheral velocity is 0.26Ö2gH and the radial velocity of flow at inlet is 0.96Ö2gH. The wheel runs at 150 rpm and the hydraulic losses in the turbine are 22% of the available energy. Assuming Radial discharge, determine
- Guide vane angle.
- Wheel vane angle at inlet
- Diameter of the wheel at inlet
- Width of wheel at inlet
