The output power for a hydraulic turbine is 40 MW at 91 rpm under a head of 19 m with an efficiency of 90 %. A model test rig can

provide a head of 8 m and absorb 47 kw.Calculate (Take the density of water as 1000 kg/m' and g = 9.81 m/s) The prototype flow rate in m'/s? The scale ratio for a model (D prototype/D model)? The model speed in rpm? The model flow rate in m/s?
