Viscosity of a Mixture

This calculates the effective viscosity of gasses.

Viscosity of a Mixture 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
