University of Virginia The Kinetic Energy of The Wind Turbine Questions

Question Description

Mass = 5216 kg

Angular velocity = 1.9 rad/s

Blade length = 38 meters

KE = 1.3 X 10^7 J

Given this information how much work did the wind provide when starting the turbine from ?=0 rad/s if the mechanism generates 10% of the kinetic energy as heat in addition to the kinetic energy of the turbines?

If the mechanism of the wind turbine can convert a max of 75% of the kinetic energy of the turbine to useful work in a minute, what is the power output of the turbine?
