Assume that a windmill blade has a radius of 50 m, and the wind is blowing at 15 mph. What would be the maximum theoretical power the windmill could produce?
What will be an ideal response?
The expression for maximum power is
Wmax = (0.593)(1.17 kg/m3)(?)(50 m)2 (15 x 0.447)3/2 = 821,192 J = 821.1 kJ
