Design a Francis turbine runner with the following data, such as net head = 68.5 m, speed = 750.2 rpm, output power = 330 kW, hydraulic efficiency = 0.945, overall efficiency = 0.85, flow ratio = 0.15, breadth ratio = 0.1, and inner diameter of runner is half of outer diameter. Also assume 6% of circumferential area of the runner is occupied by the thickness of the vanes. Velocity of flow remains constant throughout and the flow is radial at exit
