The terminal velocity of air bubbles rising through distilled water, 61% glycerine, diethylene glycol, and a solution of a surface‐active agent was measured in vertical cylindrical tubes of 2.09, 3.64, 4.91, 6.90, 9.50, and 15.25 cm. avg. I.D. An equation was developed to express a velocity‐correction factor in terms of the ratio of bubble diameter to tube diameter and an empirical constant. The constant was a function of tube diameter and of the surface tension of the liquid. It seemed to be independent of liquid viscosity.
