eng.wind-resource-assessment Calculator
Calculates wind power density, capacity factor, and annual energy from the Weibull wind speed distribution at a site. Wind power density varies with the cube of wind speed — a site with 8 m/s mean wind speed produces 5.6× more power than a 5 m/s site.
Inputs
Mean Wind Speed Ms
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Weibull K
A multiplier applied in the calculation.
Hub Height M
Vertical measurement. For health calculators, typically standing height without shoes.
Ref Height M
Vertical measurement. For health calculators, typically standing height without shoes.
Results
hub-height wind speed (m/s)
The computed height.
Weibull scale c (m/s)
Reference formula or conversion factor shown for context.
wind power density (W/m²)
Sample size or count used in the calculation.
wind class
The classification assigned based on the computed value.
capacity factor estimate
A dimensionless multiplier applied in the calculation.
