Windmill power The power P (in watts) generated by a windmill that has efficiency E is given by the formula P = 0.31ED?V', where D is the diameter (in feet) of the windmill blades and V is the wind velocity (in ft/sec). Approximate the wind velocity necessary to generate 10,000 watts if E = 42% and D = 10.
