Abstract:

A large air bubble’s buoyancy rising in still water is predicted to be significantly greater for a spherical segment, as commonly observed, than for a motionless whole sphere of equal volume from which it may have initially arisen. As a consequence, at terminal velocity the total force of friction on the large bubble is greater than it would have been if the bubble had maintained its spherical shape.
