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.

Everyday Soil Science #4: Bulk Density & Porosity
The weighty subject of bulk density relates simply to the ratio of solids (i.e., sand, silt, and clay particles) to pore space (porosity) in a given sample of soil. Bulk density typically increases as the ratio of solids in a soil increases, and conversely decreases as the ratio of solids decreases. Looked at from the porosity perspective, bulk ...

Bulk Density
Bulk density is the mass per unit volume of a loose powder bed. The unit volume includes the spaces between the particles, and the envelope volumes of the particles themselves. The method used to fill the material into that volume can affect the degree to which the powder is compressed and can thus influence the bulk density value. 14,15 Bulk …
