Electrical energy is generated by wind energy. Steady wind flows through the turbine blades at a constant speed of 24 km/h. The mechanical efficiency of turbine is 45 %. The diameter of swept circular area of the blades is 70 m. The power output from the turbine drives a generator that produces an electric power of 250 kW. Find (Let the air density be 1.18 kg/m) (10 points) a. Mass flow rate of air b. Output power from turbine Turbine-generator efficiency C.
