At a certain location, wind is blowing steadily at 5 mph. Suppose that the mass density of air is 0.0796 lbm/ft3 and determine the radius of a wind turbine with a power generation potential of 1000 kW. Express your answer in feet. Also, determine how the power generation potential (PGP) scales with wind speed, that is, find a such that PGP = Cva, where C is a constant.
