Your Questions About Wind Turbine Efficiency

Robert asks…Wind turbine efficiency question?A wind turbine and its environment can be described by the following: air density at sea level = 1kg/m3 radius of wind turbine disc = 50 m wind turbine efficiency = 75% of the Betz limit a. What is the wind turbine efficiency? (is this just 75%(16/27)...since that is 75% of bertz limit b. Calculate the power in megawatts for a wind speed of 15 m/s for the above turbine. What is the side force on the wind turbine at 15
