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