Under the influence of gravity, the lighter phase (gas) starts to rise at a constant slip velocity which is assumed to be the terminal velocity. The liquid is consequently displaced downwards. +------------+ ^ | gas | | | + | |x | liquid | +------------+ enddis ************************************************************ Group 1.
