For comparison reason consider the deepest location in the ocean which is about 11,000 [m]. If the liquid "equation of state'' (61) is used with the hydrostatic fluid equation results in
\[
\dfrac{\partial P}{\partial r} = -
{\rho_0} \text{ e}^{\dfrac{P- {P_0}}{ B_T}}
\dfrac{G}{r^2}
\label{static:eq:liquidGhydro}
\]
which the solution of equation (118) is
\[
\text{e}^{\dfrac{P_0-P}{B_T}}
=Constant -\dfrac{B_T\,g\;\rho_0}{r}
\label{static:eq:liquidGhroS}
\]
