Thermal conductivity of polyatomic gases

Input(s)

R: Gas Constant (gcm2/s2 K\left(\mathrm{g} \mathrm{cm}^{2} / \mathrm{s}^{2} \mathrm{~K}\right. gmol ))

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

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

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

Output(s)

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

Formula(s)

k=(C^p+54R)(μM)\mathrm{k}=\left(\hat{\mathrm{C}}_{\mathrm{p}}+\frac{5}{4} * \mathrm{R}\right) *\left(\frac{\mu}{\mathrm{M}}\right)
