Interaction of nonelastic incoherent spherical particles in a rapid gravity flow is analyzed. The analysis provides a refinement for the relationship between the pressure, dilatancy, and temperature of the granular medium (energy of mutual displacements of the particles). The equation of state obtained for the granular medium establishes the determined interrelation of the parameters of a rapid gravity flow of cohesionless nonelastic spherical particles and for the first time makes it possible to evaluate the effect of various forms of mutual displacement of particles on the dilatancy of the granular material during a rapid shift. The adequacy of the equation of state of the granular medium is confirmed with the use of the X-ray diffraction method.
