there is no average windspeed because all the different wetlands are in different areas some are hotter than others and some are colder so they are all different
Approximately 60,000 kwh @ annual average wind speed of 5 m/s Approximately 115,000 kwh @ annual average wind speed of 6 m/s Approximately 225,000 kwh @ annual average wind speed of 7 m/s
APPROXIMATELY 9 MPH ANNUAL AVERAGE
An anemometer is used for measuring the speed of wind,
during hurricane hazel in october of 1954 I believe the wind speed atop the empire state building recorded a wind gust to 124mph?
No. A wind vane is an instrument that can tell wind speed but not wind direction.
The current wind speed on the wind speed chart is 40 kilometers per hour.
That depends on how windy the site is. A good windy site (say 6 m/s annual average wind speed) and a 20 kW turbine could give you enough energy (on an annual basis). A less windy, less suitable site (say 4 m/s annual average wind speed) and you would need around 60 kW of turbine. These are extremely crude calculations and if you are putting in a turbine of this size then you should certainly get some wind monitoring data for the site. It is certainly a job for a professional company.
wind speed = squrt(u^2+v^2).
An anemometer measures the wind speed, and a windvan measures wind direction.
Wind speed is measured with an anemometer.
By the types of sails that you have. or it could be the wind type or the wind's speed
The wind direction is measured with wind vanes or wind socks. The wind speed is measured with an anemometer.
