Disperse Particle Separation Scientific Law
General relationship between the initial data and possibilities of estimations of disperse particle separation been found. It is stated that the sum of the ratio of the particle dispersivity characteristic to the uniform modified measure of the separation action on disperse particles and the dimensionless parameter of those uniform measure bounds from above all possible values of the relative entrainment and lets to execute a point estimation of separation degree with a priori estimation error. Furthermore, an individual estimation may be improved at the expense of complementary information with the aid of an auxiliary coefficient. The coefficient's indeterminacy equals a degree of incompliting of the initial data. All experimental data for separations of disperse particle are fully corresponding the established scientific law.
