Proposal for the Designation Method of Agitation Intensities

The stirrer speeds at which the contents of agitation vessels of various sizes come to similar states of mixing, are proportional to -2/3 power of the vessel diameters.Moreover, in these corresponding speeds, the extraction velocities of solutes between two immiscible liquids and also the dissolution velocities of solid particles are equal in all ranges of stirrer speeds.In the geometrically similar systems, powers absorbed per unit volume of agitated liquids are proportional to N3D2.From these results, it can be concluded that the agitation intensities can be measured by the power per unit volume of liquids, say H.P./m3.
