The paper deals with the effects of geometrical parameters such as the number of impellers, the vessel water height and the distance between the impellers on Newton number in a stirred tank. The mixing in single- and two-phase systems was carried out with single and multiple Rushton disk impellers. The Newton number in single-phase mixing is most affected by the number of impellers and the distance between impellers while in sparged-air dispersion it is most affected by flow and Froude number. The Newton number in two-phase systems caused due to surface aeration is affected by vessel water height and becomes constant at H_m/D > 1.22. A prediction of Newton number in a single-phase system and a two-phase system is given for single and multiple impeller stirring, as well as a prediction o f the P_g/P ratio for sparged gas dispersion. The predicted values are in good agreement with the measured ones.
