Theory and proof are presented here related to fluid pressure control of bulk solids flowability. They are directed toward a quantitative design goal for fluid-solids flow systems. An effort is made to relate multiphase system concept to existing soil mechanics, strength of material and bulk solids flow theory. Gas or liquid interstitial loads often add cumulative effects to the mechanical loads normally considered in bulk solids flow systems. Summation of the mechanical, gas and liquid loads form the basis for multiphase system design. Useful savings in design, construction and maintenance are expected from application of multiphase theory. Quantitative design can, in some cases, provide flow, no-flow, or a controlled combination of flow and no-flow.
