Isostatic depth partition of an interfacial current (source code)

= Isostatic depth partition of an interfacial current
{title2=$(\rho_0-\rho_1)h_1=-(\rho_2-\rho_0)h_2$}

<Hydrostatic pressure> continuity across both interfaces fixes the partition of current thickness. The modified current pressure is $\Delta\rho gh$, with $\Delta\rho=(\rho_0-\rho_1)(\rho_2-\rho_0)/(\rho_2-\rho_1)$. The equivalent radial <body force> is $-\Delta\rho g h_r\mathbf e_r$.
