The effect of liquid viscosity on the rate of rise of a large gas bubble through stagnant liquid in a tube is shown to be limited to that on the film flow past the bubble on the wall of the tube. A criterion of similarity between the shapes of bubbles in different liquids is obtained experimentally which enables development of a correlation for the velocities of rise. This correlation is shown to be in good agreement with experimental results for systems in which the effects of surface tension and liquid viscosity on the frontal flow are negligible.
