✦ Synopsis

Ahstrati-Laminar liquid jets used in mass transfer studies have been generally discharged from convergent nozzles or oritices. The use of long straight capillary tubes to discharge the liquid jet is studied in this work and numerical values of the jet diameter and surface velocity are obtained. These computed values are applied to predict the actual absorption rates in the laminar jet for different values of N, = Nb/Nr,, NW< and the axial coordinate. The effect of N wI is slight and can be disregarded in analyzing experimental data. Experimental values of absorption of CO3 in water and water-glycerol solutions are obtained using a laminar liquid jet discharged from capillary tube and good agreement is found between the computed values and the measured absorption rates. The results are applied to the determination of ditlusion coefficient for the CO* in water glycerol solutions.
