Viscosity of a Mixture

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

This calculates the effective viscosity of gasses.

formula

\(\mu = \frac {\sum ({\mu_i y_i \sqrt{M_i}})} {\sum ({y_i  \sqrt{M_i}})}\)

Where:

\(\mu\) (Greek symbol mu) = dynamic viscosity of the gas mixture

\(\mu_i\) (Greek symbol mu) = dynamic viscosity of a gas component

\(y_i\) = mole fraction or percent of gas component

\(M_i\) = molecular weight of gas component
