Commercially available large wind turbines have blade span diameters as large as 100 m
and generate over 3 MW of electric power at peak design conditions. Consider a wind
turbine with a 90 m blade span subjected to 25 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.
(b) The horizontal force exerted by the wind on the supporting mast of the turbine.
Take the density of air to be 1.2 kg/m3
and disregard frictional effects.
