A wind turbine designer is considering installing a horizontal axis wind turbine at a location in Michigan. To increase the powe
bogdanovich [222]

Answer:

False ( B )

Explanation:

considering that the wind turbine is a horizontal axis turbine

Power generated/extracted by the turbine can be calculated as

P =  n * 1/2 *<em> p</em> *Av^3

where: n = turbine efficiency

           <em>p = air density </em>

<em>            </em>A = πd^2 / 4

           v =  speed

From the above equation it can seen that increasing the Blade radius by 10% will increase the Blade Area which will in turn increase the value of the power extracted by the wind turbine
