Minimum Energy in Vortex Motion. 539 for the case of a circular enclosure and a small part of itswhole volume occupied by vortex, to which exigency of timelimits the present communication. 24. Commence with the vortex lining uniformly the en-closing cylinder, and the stiirer in the centre of the stillwater within the vortex. The velocity of the water in thevortex increases from zero at the inside to ^h^/a at the out-side, in contact with the boundary; according to the notationof §§ 14 and 15. Now move the stirrer very slowly from itscentral position and carry it round with any uniform angularvelocity ^^bla. A dimple, as shown in fig. 6,will be produced, running round a little in advance of thestirrer, but ultimately falling back t
