a. A model of a Kaplan turbine, built to a scale of 1/6 of the full-scale prototype, develops an output of 5 kW from a net head of 1.2 m of water at a rotational speed of 300 rpm and a flow rate of 0.5 m3 /s. Determine the efficiency of the model.
b. By using the scaling laws, estimate the rotational speed, flow rate, and power of the prototype turbine when running with a net head of 30 m.
c. Determine the power specific speed for both the model and the prototype, corrected with Moody's equation. To take account of the effects of size (scale), use the Moody formula
to estimate the full-scale efficiency, ηp, and the corresponding power
