Alarge-scale wind turbine has blades of 104 min diameter and is rated at 3.6 mw.
a. if 20 percent of the kinetic energy of the wind incident on the blades is converted into work, what wind speed is needed to produce 3.6 mw of power? (note
that the average wind speed in most of georgia is less than 5 m/s)
b. since we are converting between kinetic and mechanical energy, do you think it’s possible to achieve 100 percent efficiency?
