We investigate how the walls of cylindrical capillaries affect velocity rising gas bubbles various diameters. Of course, as capillary diameter increases, bubble will approach case free rising. Such systematic experiments on rise in capillaries, which ratio and is varied from one towards smaller values, can hardly be found literature. Experiments within system water/air have been conducted stagn...
