Hello guys,
(My first post on this forum, so ill introduce myself post scriptum)
To get into smart home systems and arduino, I am currently building a weather station measuring temperature, humidity and all kinds of funny stuff.
I am ALSO measuring the rotations of a self built 3d printed anemometer. I know the dimensions of the "flaps/cups", i know the rotations/frequency with which the thing is spinning
but i simply cant think of how to calculate the windspeed, given rotations and the drag value of a half sphere (in German its called Cw-Wert).
The actual spinning part consists of 3 equally spaced "arms" of length d each with a half sphere with diameter a.
How do I calculate the Windspeed, given those parameters?
Any hints are super appreciated.
