The analytical expositive development presented here is centered on the choked flow premise applied to two-phase, gas-liquid flow. Choked flow is a compressible fluid characteristic associated with situations where upstream conditions are decoupled from downstream conditions, e.g., the pressure at a vent is only a function of the upstream fluid state. A verbal description of choked flow is the maximization of mass transport with respect to pressure
$$ \frac{{\partial G}}{{\partial P}} \equiv 0$$
