Question

If the velocity of wind is doubled, then the power output from windmill will increase by

Answer 1

Wind speed increases then the power that can be extracted increases exponentially. Doubling the wind speed delivers eight times as much power.

Answer 2

Answer:

If wind speed doubles, the power output will increase 8 times.

Explanation:

• The cut-in speed is the point at which the wind turbine is able to generate power.
• Between the cut-in speed and the rated speed, where the maximum output is reached.
• The power output will increase cubically with wind speed.
