Bulk Density

Bulk density is the mass of bulk solid that occupies a unit volume of a bed, including the volume of all interparticles voids. Taking into account that a powder is really a particle gas mixture with both interparticle spaces and intraparticle voids (Fitzpatrick et al., 2013), three classes of bulk density have become conventional: aerated, poured, and tap.
