Abstract Velocity measurements were made on single cylindrical air bubbles rising in a variety of liquids contained in vertically mounted tubes sealed at the lower end. A general graphical correlation involving Fr = u2/gd, Eo = ρgd2/σ and Y = gμ4/ρσ3 is given. It is shown that viscous effects are of minor importance if ρ2gd3/μ2 > 3 × 105, interfacial effects if Eo > 70 and inertial if Fr < 0·003. Evidence suggests that the general correlation is also applicable to limiting velocity data for smaller (non-cylindrical) bubbles.
