... to account for the effect of gravity, which limits the film thickness for lower gas rates. Oil droplets are more effectively transported by the turbulence in the gas, so the liquid film on the pipe wall tends to have a lower aqueous fraction than the liquid layer in the bottom of the pipe. In the general...
