For the sufficiently narrow pressure range the simplest correlation is given by:

\mu(T, \rho) = \mu^*(T) \cdot (1 + \rho \cdot B^*(T))

where

fluid temperature

fluid density

some function of temperature  related to dynamic fluid viscosity at zero density 

some function of temperature  related to the second virial coefficient
