Thermal conductivity of polyatomic gases

Input(s)

R: Gas Constant $\left(\mathrm{g} \mathrm{cm}^{2} / \mathrm{s}^{2} \mathrm{~K}\right.$ gmol $)$

M: Molecular Weight $(\mathrm{g} / \mathrm{gmol})$

$\mu$: Viscosity $(\mathrm{g} / \mathrm{cm} \mathrm{s})$

$\hat{\mathrm{C}}_{p}$: Specific Heat $(\mathrm{cal} / \mathrm{g}-\mathrm{mol} \mathrm{K})$

Output(s)

k: Thermal Conductivity $(\mathrm{W} / \mathrm{m} \mathrm{K})$

Formula(s)

$$ \mathrm{k}=\left(\hat{\mathrm{C}}_{\mathrm{p}}+\frac{5}{4} * \mathrm{R}\right) *\left(\frac{\mu}{\mathrm{M}}\right) $$
