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.
