Formula 12.39

Pan-Maddox equation for molecular weight

Input(s)

$\mathrm{T}_{\mathrm{b}}$: Boling Temperature $(\mathrm{K})$

$\gamma$: Relative Density at 15.5 Degrees $(\mathrm{g} / \mathrm{cc})$

Output(s)

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

Formula(s)

$$ \mathrm{M}=1.66 *\left(10^{-4}\right) *\left(\mathrm{~T}_{\mathrm{b}}^{2.2}\right) *\left(\gamma^{-1.02}\right) $$
