WebDec 21, 2024 · In general, the viscosity of air is only slightly dependent on the pressure but is strongly related to temperature.. The dynamic viscosity directly correlates with the square root of temperature μ ∝ √T, and density is inversely proportional to temperature: ρ ∝ 1/T.Therefore, we can relate these two proportionalities and derive the relationship … WebNov 18, 2024 · Air temperature; Air pressure; Relative humidity; The method of calculating air density is given as below: Calculate the saturation vapor pressure at a given temperature ‘T’ by using, p 1 = 6.1078 * 10^ [(7.5 * T)/( T + 237.3)] Where ‘T’ is measured in degrees celsius. Find actual vapor pressure by the given formula: p v = p 1 * R H
