Problem 2. Consider a wind turbine with a 75-m blade span subjected to 25- 25 km/h km/h steady winds. If the combined turbine-generator efficiency of the wind turbine is 32 percent, determine (a) the power generated by the turbine and (b) the horizontal force exerted by the wind on the supporting mast of the turbine. Take the density of air to be 1.25 kg/m³, and disregard frictional effects on the mast. Hint: How does the energy extracted by the turbine impact the outgoing air velocity? 75 m
