anemometer is a Mathematica package which calibrates an anemometer scale with the wind speed instead of the deflection angle, by Jim Fink.
Note from Jim Fink: "One of my class projects had the students making a crude anemometer consisting of a ping-pong ball suspended from a string. The stronger the wind, the greater the deflection. The anemometer the kids made had a simple angular-deflection scale, but I wondered how one would calibrate the scale with the wind's speed instead of the deflection angle to make the anemometer more meaningful and useful."
"So I did a little physics, assumed the wind pressure is proportional to the square of the wind's speed (a standard first approximation), and asked Mathematica to plot the result for a particular set of parameters. Attached is a Mathematica notebook with the plots. I'm not sure how one might mark the scale, but I'd probably choose equal angle deflections and mark the deflections with the corresponding wind speed (first plot)."
