Here, the transport properties are:

=  viscosity

=  dilatational viscosity (zero for dilute monatomic gases)

 =  thermal conductivity

=  thermal diffusion coefficients

=  generalized Fick multicomponent diffusion coefficients

= generalized Maxwell-Stefan multicomponent diffusion

 coefficients

An equation relating the and the was given for the first time by Curtiss and Bird [3], based on the method suggested by Merk [4], who studied the connection as a graduate student while at the Technical Hogeschool in Delft.

1f.  The transport properties in terms of molecular parameters

All that remains is to get the transport properties in terms of the constants appearing in the intermolecular force law. Such calculations have been done for several force laws (see MTGL, Chapter 8). For the simplest properties, namely, self-diffusivity, viscosity, and thermal conductivity of pure monatomic gases, we have the following formulas:

Self diffusivity(1.17)
