Surface tension from density

Input(s)

P: Pressure $\left(\right.$ dyn $\left./ \mathrm{cm}^{2}\right)$

M: Molecular Wt (gms)

$\rho_{1}$: Liquid Density $(\mathrm{g} / \mathrm{cc})$

$\rho_{\mathrm{v}}$: Vapor Density $(\mathrm{g} / \mathrm{cc})$

Output(s)

$\omega$: Surface Tension $(\mathrm{dyn} / \mathrm{cm})$

Formula(s)

$$ \omega^{0.25}=\left(\frac{\mathrm{P}}{\mathrm{M}}\right) *\left(\rho_{\mathrm{l}}-\rho_{\mathrm{v}}\right) $$
