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