These methods are based on measurements of global properties, such as mixing-power minimum and gas-holdup maximum, and a method based on the local interfacial characteristics of two-phase systems. The experiments were performed by dispersing air into water and air partly into water-carboxy-methyl cellulose (CMC) solutions of different concentrations. A comparison of the results of the different methods is shown, as well as a comparison with the results from criteria found in the literatureV prispevku so obravnavane nekatere metode, s katerimi lahko na različne načine zaznamo poplavno stanje pri dispergiranju plina v kapljevino v posodi z enojnim Rushtonovim mešalom. To so metode merjenja splošnih veličin, npr. najmanjša moč mešala in največji prirastek plinaste faze ter metoda zaznave lokalnih karakteristik faznega stika. Preskus je potekal pri dispergiranju zraka v vodo ter delno pri dispergiranju zraka v vodno raztopino karboksi-metil-celuloze (KMC) različnih koncentracij.
