Fresh water-filled porosity (fresh-water-bearing limestones)
Input(s)
\(\rho b\): Bulk Density \(\left(\mathrm{g} / \mathrm{cm}^{3}\right)\)
\(\rho l s\): Limestone Density \(\left(\mathrm{g} / \mathrm{cm}^{3}\right)\)
\(\rho w\): Water Density \(\left(\mathrm{g} / \mathrm{cm}^{3}\right)\)
Output(s)
\(\Phi\): Water Filled Porosity (fraction)
Formula(s)
\[
\Phi=\frac{\rho l s-\rho b}{\rho l s-\rho w}
\]
