In materials science, bulk density, also called apparent density, is a material property defined as the mass of the many particles of the material divided by the bulk volume. Bulk volume is defined as the total volume the particles occupy, including particle's own volume, inter-particle void volume, and the particles' internal pore volume.

Bulk density, on the other hand, is a measure of the mass of a material per unit volume, including the void spaces between particles. It takes into account the total volume occupied by both the solid material and any voids present. Bulk density is denoted by the symbol "γ" (gamma) and is also expressed in units like kg/m³ or g/cm³.

Mar 11, 2014 · Bulk density is the weight of a volume unit of powder and is usually expressed in g/cm 3, kg/m 3, or g/100 ml. Bulk density is usually determined by measuring the volume of 100 g of powder in a 250 ml graduated cylinder after exposure to compaction by standardized tapping.

Nov 21, 2023 · Bulk density, or dry bulk density, is a property of soils and other masses of particulate material. It's the weight of the particles of the soil divided by the total volume.

Jan 30, 1996 · The meaning of BULK DENSITY is the density of a given amount of particulate matter (such as a powder). How to use bulk density in a sentence.

Soil bulk density can be defined as the mass of solid particles in a given volume of soil. These soil solids include mineral particles, such as sand, silt, clay and organic matter. Bulk density measurements are used to determine the compactness of soil.

BULK DENSITY definition: 1. the relationship between the mass of a substance and the space that it takes up: 2. the…. Learn more.

Apr 12, 2025 · Bulk density is determined by dividing the total mass of a material by its total volume, including any void spaces. The formula for bulk density is: Bulk Density = Total Mass / Total Volume.

Feb 6, 2023 · Bulk density refers to the mass of the bulk powder divided by the bulk volume. Bulk density can be calculated through the formula below: where ρB is the bulk density, M is mass in grams, and VB is the bulk volume in milliliters. The bulk volume includes the volumes of the particle solid, interparticle voids, and pores in the particles.

Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha). The soil bulk density (BD), also known as dry bulk density, is the weight of dry soil (M solids) divided by the total soil volume (V soil).
