For the sufficiently narrow pressure range the simplest correlation is given by:
| LaTeX Math Block |
|---|
|
\mu(T, \rho) = \mu^*(T) \cdot (1 + \rho \cdot B^*(T)) |
where
| fluid temperature |
| fluid density |

| body | --uriencoded--\mu%5e*(T) = \mu(T, \rho =0) |

|
| some function of temperature related to dynamic fluid viscosity at zero density |
| = 0| LaTeX Math Inline |

| body | --uriencoded--B%5e*(T) |
