Blade Tip

how would you calculate the wind speed if you know the rpm?

I am making a code on how to calculate the wind speed given the rpm. I am making an anemometer.
The anemometer will be made out of three hemispherical cups connected to the rotating shaft.

After 1 revolution, the blade tip has travelled 2πr units of length (feet, metres etc)
So just multiply this figure by the number of revolutions per minute to get the peripheral distance travelled in a minute.

Bear in mind that this will give the answer if feet/metre per minute and you may then want to convert this into mph or kph.
