4) Design a wind turbine with a rotor radius of 25 meters, use your optimum wind speed and finally estimate the power output. (take cp as 0.4; p = 1.225 kg/m) Wind Power Equation P ==-xpxAxvxc where, P is the power in Watts, p is the air density in kg/m, A is the rotor area in m, v is the wind speed in m/s, cp is the power coefficient Betz limit says that no wind turbine can convert more than 59.3% of the kinetic energy of the wind into mechanical energy turning a rotor, i.e cpmax=0.593.
