  2. Wind profile power law - Wikipedia

    en.wikipedia.org/wiki/Wind_profile_power_law

    The power law is often used in wind power assessments [4] [5] where wind speeds at the height of a turbine ( 50 metres) must be estimated from near surface wind observations (~10 metres), or where wind speed data at various heights must be adjusted to a standard height [6] prior to use.

  3. Barometric formula - Wikipedia

    en.wikipedia.org/wiki/Barometric_formula

    Values of ρ b of b = 1 through b = 6 are obtained from the application of the appropriate member of the pair equations 1 and 2 for the case when h = h b+1. [ 2 ] In these equations, g 0 , M and R * are each single-valued constants, while ρ , L , T and h are multi-valued constants in accordance with the table below.

    Buildings in the Petaling Jaya suburb of Kelana Jaya were previously capped at 15 floors (around 50–60 m (160–200 ft) in height) because of the close proximity to Subang International Airport, less than 5 km (3.1 mi) away. The height restriction was lifted in 1998 when commercial jet operations were relocated to the Kuala Lumpur ...

    Flight levels [3] are described by a number, which is the nominal altitude, or pressure altitude, in hundreds of feet, and a multiple of 500 ft.Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320".

    Similarly, for open terrain (grassland) the typical range is 0.01-0.05 m. [2] For cropland, and brush/forest the ranges are 0.1-0.25 m and 0.5-1.0 m respectively. When estimating wind loads on structures the terrains may be described as suburban or dense urban, for which the ranges are typically 0.1-0.5 m and 1-5 m respectively. [2]
