Torque on an anemometer

  1. Dec 12, 2004 #1
    Is it possible to calculate the torque on an anemometer, of radius x with cupradius y, depending on the wind speed?
    If not is there a similar horizontally rotating device with which you can calculate the torque?

    If the anemometer is turning at a constant speed, and we assume that the bearings it is turning on are frictionless, then the torque is zero.
