Scaling of hydraulic turbine - GATE ME '07

in Thermodynamics Forum

A model of a hydraulic turbine is tested at a head of 1/4th of that under which the full-scale turbine works. The diameter of the model is half of that of the full-scale turbine. If N is the RPM of the full-scale turbine, then the RPM of the model will be A. N/4 B. N/2 C. N D. 2N
