A steady wind is blowing at 8 m/s at 200 m above ground level. Estimate the wind

Question:

A steady wind is blowing at 8 m/s at 200 m above ground level. Estimate the wind power at a height of 10 m above a large open cropped field. Approximately what height is needed for a turbine in a small town to reach wind flowing with the same power?
