Error percentage of porosity measurements

Input(s)

$\emptyset_{m}$: Measured Porosity (fraction)

$\phi_{p s}$: Calculated Porosity or Pseudo-Porosity (fraction)

Output(s)

$E_{\emptyset}$: Effective Porosity (fraction)

Formula(s)

$$ \mathrm{E}_{\varnothing}=\frac{\varnothing_{\mathrm{m}}-\varnothing_{\mathrm{ps}}}{\varnothing_{\mathrm{m}}} \cdot 100 $$
