Viscosity Methods for Vapor Phase

The vapor viscosity calculation method may be selected with the drop-down list box. Options for vapors include:

None

No vapor viscosities are computed.

Pure Component Average

Vapor viscosities are computed by appropriate averaging of the pure component values from the library.

Petroleum Correlation

Vapor viscosities are computed using generalized methods for hydrocarbons - not available with Electrolyte Models.

TRAPP Correlation

Vapor viscosities are computed using the TRAPP method.

Lohrenz-Bray-Clark

Vapor viscosities are computed using the Lohrenz-Bray-Clark method.

User-added Methods

This option specifies that vapor Viscosities will be calculated with a User-added subroutine (UTRAN1 - UTRAN5) that has been linked into PRO/II.

Bromley Wilkey Correlation

Vapor viscosities are computed using the Bromley Wilkey correlation.

NIST23

Vapor viscosities are computed using the NIST23 method.

GERG08

Vapor viscosities are computed using the GERG08 method.

AGA8

Vapor viscosities are computed using the AGA8method.
