✦ Synopsis

Abstrae-A

new method for the calculation of drop sizes in pulsed sieve-plate extraction columns is reported. Under certain assumptions for the motion df the drops in the vicinity of the plates, it is possible to develop an equation that is confirmed by measurements in a much greater range, especially of the pulsation intensity, than other equations being known up to now. Additionally, a dependence of the drop diameter on the hole diameter at constant fractional free area results from that new equation, which has been proven so far only experimentally. Finally, with the developed equation under consideration of the time-dependent variations of the effective forces it is possible to make qualitative predictions on the type of the drop size distribution to be expected.
