A three-blade wind turbine has a rotor diameter of 100 meters and a hub height of 80 meters. If wind power at this site varies as the ratio of heights raised to the 1/7 power, compute the ratio of power in the wind that appears at the tip of the top blade relative to the power that appears at the elevation at the tip of the bottom blades. Express to 3 decimal places. Assume the blades are located at 90° (straight up), 210°, and 330°.
