Kinematic Viscosity of Air 空气的运动粘度 Prandtl Number Air 空气的普朗特尔数 The viscosity of air depends mostly on the temperature. At 15 °C, the viscosity of air is 1.81 × 10-5 kg/(m·s) , 18.1 μPa·s or 1.81 × 10
Online calculator, figures and tables with dynamic (absolute) and kinematic viscosity for air at temperatures ranging -100 to 1600°C (-150 to 2900°F) and at pressures ranging 1 to 10 000 bara (14.5 - 145000 psia) - SI and Imperial Units.
Therefore, we can relate these two proportionalities and derive the relationship between kinematic viscosity and temperature as ν = T3/2. As you can see now, when the temperature rises, the viscosity of the air increases. This distinguishes air and most gases from the viscosity of liquids. ...
Provide a molecular interpretation for the observation that the viscosity of a gas increases with temperature, whereas the viscosity of a liquid decreases with increasing temperature. Using the examples of solid honey in the cold and dripping honey in the heat, ex...

The viscosity index (ASTM D2270) is a widely used measure of the variation in kinematic viscosity due to changes in the temperature of fuels between 40°C and 100°C (104°F and 212°F). From: Encyclopedia of Analytical Science (Third Edition), 2019 ...

Viscosity reporting is only valid when the temperature at which the test was conducted also is reported - for example 23 cSt at 40 degrees C. Of all the tests employed for used oil analysis, none provides better test repeatability or consistency than viscosity. Likewise, there is no property ...
