They assumed that ligament formation from the rim of a drops on the rim of a spinning disc along its vertical width disc can be considered to occur from a circular disc like is shown in Fig. 1. sheet whose radius r is equivalent to the above thickness h.

It should be noted that the vertical width is of the order It has however been demonstrated [6] that drop or ligament of a wave length, hm.
