Viscosity of a Mixture

This calculates the effective viscosity of gasses.

Viscosity of a Mixture formula

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

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
