A model of a Francis turbine is built to a scale of 1/5 of full size and when tested it developed a power output of 3kW under a head of 1.8 m of water, at a rotational speed of 360 rev/min and a flow rate of 0.215m3/s. Estimate the speed, flow rate, and power of the full-scale turbine when working under dynamically similar conditions ahead of 60 m of water. By making a suitable correction for scale effects, determine the efficiency and the power of the full-size turbine. Use Moody’s formula and assume n = 0.25.
