The wind turbinegenerator shown has an output-power rating
Chapter 14, Problem 14.78(choose chapter or problem)
The wind turbine–generator shown has an output-power rating of 1.5 MW for a wind speed of 36 km/h. For the given wind speed, determine (a) the kinetic energy of the air particles entering the 82.5-m-diameter circle per second, (b) the efficiency of this energy conversion system. Assume \(r=1.21\mathrm{\ kg}/\mathrm{m}^3\) for air.
