Isothermal compressibility of water - Osif correlation

Input(s)

$\mathrm{C}_{\mathrm{NaCl}}$: Salinity $(\mathrm{g} \mathrm{NaCl} / \mathrm{L})$

$\mathrm{T}$: Temperature $(\mathrm{F})$

p: Pressure (psi)

Output(s)

$c_{w}$: Isothermal Compressibility of Water (Osif Correlation) (SCF/STB)

Formula(s)

$$ c_{w}=\frac{1}{7.033 * p+541.5 * C N a C l-537.0 * T+403300} $$
