Wind provides a source of renewable energy that is increasingly being tapped. Modern wind tubines can conbert up to 30% of the kinetic energy of the incoming wind blowing through their blades to electicity. Assuming that the wind at a proposed offshore location blows steadily at 20 knots, how much electrical power can be generated from a turbine with rotor diameter d=80m? By how much is the wind slowed when going through the turbine? Temperature of the air is 300K and its pressure is 1 bar. Air can be considered an ideal gas with Cv= 5R/2?
