Total required annual electrical energy output from the wind farm =120 TJ Max number of turbines for which there is space on the farm =20. Average annual wind speed at the site= 9.0 ms^-1
a) Deduce that the average power output required from one turbineis 0.19 MWb) Estimate the blade radius of the wind turbine that will give0.19 MW Power output. (density of air= 1.2 kg m^-3)
