How is wind speed calculated
WebThe ratio of wind speed and shaft speed is called the anemometer factor, and it varies depending on the physical construction of the unit, typically ranging from 2 to 3. Wind speed is calculated as follows: Instantaneous Wind Speed = Anemometer Factor x Instantaneous Shaft Speed. Average Wind Speed = Anemometer Factor x (Number of Turns / Time) Web30 jan. 2024 · Phillipa K. Gillingham, in Advances in Ecological Research, 20244. 1. 5 WindAnemometers, devices used to measure wind speed, generally fall into three categories. The cheapest and most widely used in ecological studies are cup or propeller anemometers, in which rotating cups or a propeller is driven by the wind.
