The water enters the blades of the Francis turbine at an angle of 30 and leaves in radial direction. The blades are rotating at 40 rad/s and they discharge water at 0.5 m3/s. The blades have a width of 500 mm and the impeller radius for entrance and exit turbine are 1200 mm and 400 mm respectively. The turbine operates under a total head of 2 m. 1. Draw the blade velocity diagram for the turbine entrance. 2. Determine the torque and power the water supplies to the turbine shaft, also the hydraulic efficiency.
