The particle mass density or particle density of a material (such as particulate solid or powder) is the mass density of the particles that make up the powder. Particle density is in contrast to the bulk …

The material density or true density of a solid or powder is the density of the particles that make up the powder, and is defined as the ratio of particle mass to its actual volume, excluding internal pores.

Particle density is a measure of the mass of soil solids per given volume (g/cm3 ); however, pore space is not included as it is with bulk density. Particle density is similar to the specific gravity of a solid and …

The dry weight of soil per unit volume of soil; most often expressed on a soil volume basis, rather than on a particle basis. Bulk density considers both the solids and the pore space; whereas, particle …

What is Bulk Density and Particle Density? Definition: Bulk density includes the volume of voids between particles, while particle density measures only the solid material excluding voids.

Particle density, ρs, is a physical property of soil, defined as the mass per unit volume of soil solids, reported in grams per cubic centimeter (g/cm3:: metric).

Jul 16, 2025 · Particle density, also known as bulk density, is a fundamental soil property that represents the mass of solid soil particles per unit volume. It is expressed in units like grams per cubic …

The expression particle density refers to the number of particles per unit volume, not to the density of a single particle, and it is usually expressed as n.

Particle density is a physical property that describes the mass of a particle divided by its volume. It can be measured using either the pycnometer method or the submersion method.

The particle density of a soil = dry mass (g) of soil / volume of soil particles. Where D p is particle density; ODwt is oven-dry weight of soil; V s is volume of solids.
