bulk density
Technical term used in materials science, engineering, and powder technology. Refers to the mass of a particulate material divided by the total volume it occupies, including void spaces.
Measure the bulk density of the powder.
Compound of 嵩 (かさ, 'bulk, volume') and 密度 (みつど, 'density'). The exact historical derivation is uncertain; the term is a modern technical coinage.
