A Francis turbine is required to give 180 kW output power under

A Francis turbine is required to give 180 kW output power under a net head (H) of 17 m. The efficiency is 80%. The turbine speed is 600 rpm. The flow velocity (V.) is constant and equals 0.3(2gH)2, peripheral velocity (u) at inlet equals 0.6(2gH) and the flow is radial at exit. Determine; i. The diameter of the runner at inlet, ii. The guide vane angle, iii. The runner blade angle at inlet and iv. The width of the runner at inlet assuming blades thickness occupied 15% of the circumference.
