How do I measure wind speed?
Wind speed is measured with an anemometer. Most anemometers have four horizontal shafts arranged like the spokes of a wheel. The end of each shaft is cup-shaped. The wind pushes the concave side of the cup more than the convex side so the anemometer spins in the wind.
How do you measure wind speed without an anemometer?
