3. To avoid flow interactions, turbines must be placed at reasonable distances apart. In one farm layout, the towers are spaced 3 rotor diameters apart in the direction perpendicular to the wind, while they are 6 rotor diameters apart parallel to the wind: 6D Hub height-D A utility company is proposing to develop the largest wind farm in the world, which would exceed the Alta Wind Energy Center capacity of 1548 MW The farm will use turbines with a 90-m diameter, and the average wind speed at the site is 21 mph. The wind follows the Rayleigh distribution, and its density at this elevation is 1.1 kg/m3. a. Assuming operation at the Betz limit, what is the maximum power, P (in W), that may be generated by a single turbine at this site? b. How many turbines, Ni, will be needed to generate the needed capacity? c. What is the minimum area, Afarm (in km2), required for the wind farm?
