   These values refer to well-developed wind waves of the open sea. The lag effect between the wind getting up and the sea increasing should be borne in mind. To convert knots to mph multiply by 1.15, for m/s multiply by 0.514. The Beaufort scale, which is used in Met Office marine forecasts, is an empirical measure for describing wind intensity ...

   engineering.stackexchange.com › questions › 6144

   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 ...

   How fast does a wind sway a tree?

   • Land: Trees sway, walking in the wind is difficult. Wind speed: 17.2–20.7 m/s (39–46 mph). Wave height: 5.5–7.5 m (18–25 ft). Sea: moderately high waves, edges of crests begin to break into spindrift. Land: Twigs and branches break off of trees. Wind speed: 20.8–24.4 m/s (47–54 mph).

   What is the highest wind speed in a hurricane?

   • 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.

   How does wind affect a plane's speed?

   • If the aircraft is heading North, say, at a speed of 100 knots, and the wind is from the southwest at a speed of 30 knots, meaning the air containing the aircraft is moving Northeast at 30 knots, those two vectors are added to get the aircraft's actual motion vector over the ground, which is roughly to the East of North, and roughly 120 knots.

   How do you travel a distance with head wind?

   • Using simple algebra uground = uIAS +uwind u g r o u n d = u I A S + u w i n d So to travel a distance S S with head wind takes tA→B = S uIAS−uwind t A → B = S u I A S − u w i n d, but to return with tail wind tB→A = S uIAS+uwind t B → A = S u I A S + u w i n d. Obviously tA→B>tB→A t A → B> t B → A

   0. Wind speed affects ground speed, not air speed. The airplanes fly at a specified IAS (indicated air speed). Add the IAS with the wind speed in the direction of travel and you get the ground speed. Using simple algebra. uground = uIAS +uwind u g r o u n d = u I A S + u w i n d.
