WebWind measurement is composed of two complementary parameters: its speed (or force) and its direction. The units of measurement of wind used in the UK are km/h or m/s for its speed, and knots (1 knot = 1.852 km/h) which are mainly used by sailors and pilots. Web26 jan. 2010 · P = Power output, kilowatts. Cp = Maximum power coefficient, ranging from 0.25 to 0.45, dimension less (theoretical maximum = 0.59) ρ = Air density, lb/ft3. A = …
