The potential power output in Watts of a windmill can be approximated by
P=12CρAv3where C is the capacity, ρ is the air density, A is the swept area, and v wind speed. Use the power potential to find the potential power output in Watts of a windmill of blades 25 meters long operating with 10% capacity if the wind is blowing 5 meters per second with air density 1.21 kgm2. Round your answer to the nearest integer, if needed.
swept area= 1963.49

Question

The potential power output in Watts of a windmill can be approximated by
