.... For the low gas rate USG1, there is only a single relatively high solution 1 for the liquid holdup. If the gas rate is changed to high rate USG3, still only a single solution exists; however, 3 is a relatively low solution for the liquid holdup compared to 1. For the intermediate gas rate USG2 the liquid...
