Definition

mass density of a particulate material that is the mass per total bulk volume occupied by the material, where the total bulk volume includes particle volume, pore volume within particles, and void volume between particles

Explanatory Notes

The total bulk volume is the volume occupied by the particulate material prior to any intentional compaction, mechanical tapping, or vibration.

Examples

• the bulk density of powdered cell culture medium; the bulk density of granulated medium; the bulk density of chromatography resin beads; the bulk density of an excipient powder lot;

Synonyms

• apparent density

Primitive Class

This class is declared primitive and it does not have necessary and sufficient condiftions defined.

Primitive Rationale

There are insufficient constructs for creating a set of necessary and sufficient conditions.

Formal Axioms

First-Order Logic Axioms

BulkDensity(x) → MassDensity(x) ∧ ∃m (MaterialEntity(m) ∧ qualityOf(x, m) ∧ ∃f (ParticulateForm(f) ∧ hasQuality(m, f)))

Semi-Formal Natural Language Axioms

if x is a ‘bulk density’ then x is a ‘mass density’ that is the ‘quality of’ some ‘material entity’ that ‘has quality’ some ‘particulate form’
