Isothermal compressibility of limestones (Newman correlation)

Input(s)

$\phi$: Porosity (fraction)

Output(s)

$\mathrm{C}_{\mathrm{t}}$: Compressibility $\left(\mathrm{psi}^{-1}\right)$

Formula(s)

$$ \mathrm{Ct}=\frac{97.32 * 10^{-6}}{(1+55.8721 * \emptyset)^{1.42869}} $$

Notes: Check for $0.02<\varnothing<0.23$.
