Transport Property Evaluation


This spreadsheet will calculate transport properties for gas mixtures of two or more species. Binary and mixture properties are computed for binary mixtures. When three or more species are present, multicomponent properties are also evaluated.





Currently, at least two species must be specified. If one species is present in excess, such as a bath gas or diluent, list it first.
