Power (W) = 1/2 x density
of air x Area in meters x velocity cubed
60 miles/hour is 26.82 meters/second
The standard density of
air is 1.225 kg/m3
Thus, using a scoop
with a 2ft diameter
1 ft. is 0.3048 meters
1 mph = 0.447 m/s
(divide speed by 2.237)
Power (W) = 1/2 x 1.225 x
(.3048 squared x 3.1416) x ((60/ 2.237) cubed) = 3,449 watts or 3.4 kW
So, a car traveling at 60
mph will create 3.4 kilowatts of power. The rotor will turn.
Torque = ((wattage / 745) x 5252) / RPM
