Wind Power The electrical power generated by a
windmill varies jointly with the square of the diameter
of the area swept out by the blades and the cube of the
wind velocity. If a windmill with a 10-foot diameter
and a 16-mile-per-hour wind generates 15,392 watts,
how much power would be generated if the blades
swept out an area 12 feet in diameter and the wind
speed was 15 miles per hour?
P = 15,392W x (12ft/10ft)^2 x (15mph/16mph)^3
P = 15,392W x 1.440000 x 0.8239746
P = 18,263W <==ANSWER
