To find: The factor that increases the power generated by wind turbine if it is having tripled wind speed.

Answer to Problem 64PPE
The factor that increases the power generated by wind turbine if it is having tripled wind speed is
Explanation of Solution
Given information: The power generated by a wind turbine depends on the wind speed. The expression that gives the power in watts for a certain wind turbine at wind speed
Calculation:
Let the power and speed of a wind turbine be
The expression for the power in watts for a certain wind turbine is:
The wind speed
Substitute
On comparing the above expression and given expression of power in watts, the power generated by the wind turbine is increased by a factor of
Therefore, the factor that increases the power generated by wind turbine if it is having tripled wind speed is
