Viscosity of a Mixture

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

This calculates the effective viscosity of gasses.

Viscosity of a Mixture formula

\(\large{ \mu = \frac {\sum \;\left({\mu_i \; y_i \; \sqrt{M_i}}\right)}{\sum\; \left({y_i \; \sqrt{M_i}}\right)}   }\)       

Where:

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

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

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

\(\large{ M_i }\) = molecular weight of gas component
