A 20 MW radial flow hydraulic turbine is to be designed with a head of 70 m, and a speed of 90 RPM. A geometrically similar model with an output of 70 kW and 8 m head is to be tested under dynamically similar conditions. At what RPM should the model be run? What is the required impeller diameter ratio between the model and prototype and what is the volume flow rate through the model if the efficiency is 0.88?
