Abstract Characteristic velocity is investigated in agitating extraction column of 90mm diameter.Four systems:kerosene water,kerosene 15%glycerol, machinery oil water,2 ethyl hexanol water are used in this work. In term of experimental data, a fluid mechanics model was determined by regression analysis and compared with other equations. Experimental results of this work show that characteristic velocity has two regions with different characteristics. The correlations of characteristic velocity in the two regions and the critical rotation speed were obtained.
