    applies this principle to relate a mixture to methane as a reference fluid. The viscosity correlation used for the reference fluid involves 20 coefficients. This program has an accuracy for methane of over 3% average absolute deviation (AAD). This can be considered a lower limit of the uncertainty expected for this program when applied to estimation of the viscosity of a mixture of gases. The ...
