Extension of Johnson's equation of homogeneity of random mixtures.
The volume-weighted/volume-number mean particle diameter of the ingredient is applied to the equation of Johnson (1972) as a measure of the mean particle size defining the degree of homogeneity of random mixtures. By introducing the volume shape factor, the applications of this equation are extended to ingredients of nonspherical particle shape.
