# Reference dynamic viscosity of gas

Used in Sutherlands model vor dynamic viscosity of ideal gases at $T_{gas0}$.

The sources are:

• Values are taken from Wikipedia and the book 'Air Pollution and Greenhouse Gases' by Z. Tan (2014)
• Value for SF6 is taken from 'Gravitational Transport of Particles in Pure Gases and Gas Mixtures' by Dr. S.K. Dua et al. (2007)
• Value for Ne is taken from 'Analysis of Sutherland Constant from Coefficient of Viscosity of Gases Using Attractive Potential Model' by J.N. Mandal & S.N. Roy (2016)

Note: 1 Pa = 1 kg/(m.s$^2$)
