It is shown that the porosities of multi-size mixtures of particles can be calculated with confidence by regression methods and with minimum measurements-seven in the case of ternary systems. Calculated and measured porosities are given for ternary systems of uniform and non-uniform mixtures of spherical particles and for mixtures of irregular-shape particles (coke). The results show that calculated porosities are in all cases within 2% relative error of measurements and that these predictions are superior to those of the geometrical/ mathematical models thus far developed.
