1. 1. The coefficient of viscosity of air has been measured by the comparative transpiration method over the temperature range 23°850°C. Particular attention has been paid to points raised in criticisms of Williams''s work, and the method which he used has been completely vindicated.2. 2....

For gasses, viscosity increases with temperature as the free motion of gas molecules is enforced. For example, the viscosity of water, μwater, is 10−3 Pa s at 20 °C, while that of plasma is 1.6 × 10−3 Pa s at 37 °C, and that of air at room temperature (18 °C) is ...
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 the...

While the effect of pressure below p < 1000 bar is negligible (Siegloch, 2009) in a common stirred bioreactor with aqueous broth the effect of temperature is often prevailing. As an example, the viscosity of pure water at 20 °C differs from the one at 50 °C by more than 40% (see...
