Wind (km/h) = 3.6 × Wind (m/s) Wind (km/h) = 1.852 × Wind (kts) Wind (m/s) = 0.44704 × Wind (mph) Wind (m/s) = 0.2777778 × Wind (km/h) Wind (m/s) = 0.5144444 × Wind (kts) Where: Wind (kts) is the wind speed in knots, Wind (mph) is the wind speed in miles per hour, Wind (km/h) is the wind speed in kilometers per hour, Wind (m/s) is the wind ...
v = 0.836 B 3/2 m/s; v = 1.625 B 3/2 knots (=) where v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number. For example, B = 9.5 is related to 24.5 m/s which is equal to the lower limit of "10 Beaufort". Using this formula the highest winds in hurricanes would be 23 in the scale.
Q8. The sketch below shows a wind turbine. (a) At a particular wind speed, a volume of 2.3 × 10 4 m 3 of air passes the blades each second. The density of air is 1.2 kg/m 3. Calculate the mass of air passing the blades per second. (b) The power output of the turbine is directly proportional to the kinetic energy of the air passing the blades ...
Wind Speed Conversion Formulas: Conversion formula for Miles per hour to Knots: Wind (kn) = 0.8689762 x Wind (mph) Wind (mph) = 1.1507794 x Wind (kn) Conversion formula for miles per hour to meters per second: Wind (m/s) = 0.44704 x Wind (mph) Wind (mph) = 2.23694 x Wind (m/s) Conversion formula for miles per hour to kilometers per hour:
Nov 15, 2015 · I'm trying to understand and identify the equations to use in defining the relationship between wind velocity, turbine rotor diameter, and power output for a wind turbine. To simplify my question, let's use the following assumptions: Average wind speed of 8 m/s. Rotor length of 40m for an overall diameter of 80m.

The formula for calculating wind on the Beaufort wind force scale is the following: v = 0.836 B3/2 m/s. Where: V is the wind speed at 10 meters above the sea (by the way, this is the standard height for all wind measurements). B is the Beaufort scale number. For example, Beaufort scale 8 is equivalent to 20 m/s wind speed, wind force 10 on the ...
