Velocities of a air plug rising through stagnant water in inclined annuli were examined on the effects of inclination of tubes, clearances between an outer tube and inner tubes and plug volume. The inside diameter of outer tube is 60mm and seven kinds of tubes with the differed outside diameter were used as the inner tube. The plug behavior due to inclination of tubes and clearances of passages is very complicated and the plug form and velocity were greatly influenced by them.
