Ineffective porosity

Input(s)

$\mathrm{V}_{\text {dis }}$: Volume of Completely Disconnected Pores $\left(\mathrm{cm}^{3}\right)$

$\mathrm{V}_{\mathrm{b}}$: Bulk Volume $\left(\mathrm{cm}^{3}\right)$

Output(s)

$\varnothing_{\text {in }}$: Ineffective Porosity (fraction)

Formula(s)

$$ \emptyset_{\mathrm{in}}=\frac{\mathrm{V}_{\mathrm{dis}}}{\mathrm{V}_{\mathrm{b}}} $$
