It is the difference between the density of a bulk sample, and the density of a homogenous piece of the material being measured.
The difference between the density of a pile of gravel, and one stone from the pile, for example. the pile is less dense.
Or styrofoam peanuts versus polystyrene plastic, the same material in a different form.
Used more in engineering, for things like earthfill, coal hauling, etc.

Density refers to the mass of a substance per unit volume, while bulk density is the mass of a mixture or material divided by its total volume including voids. Bulk density takes into account the space between particles and is often used in industries such as agriculture and mining to estimate the amount of material that can be stored or transported.

Why is parameter bulk density more used than particle density?
Bulk density is more useful because it accounts for the spaces between particles in a material, reflecting how closely packed the material is in real-world applications. Particle density only considers the intrinsic density of the material itself and does not provide information on how the material behaves in a bulk form. Therefore, bulk density is more relevant for practical purposes such as determining flow properties, storage requirements, or compaction characteristics.
Why is bulk density a more meaningful figure than particle density in terms of practical agriculture than particle density.?
Bulk density is more meaningful in agriculture because it incorporates the pore space between soil particles, which affects root development, water infiltration, and aeration. Particle density, on the other hand, only accounts for the density of soil particles without considering the spaces between them. Therefore, bulk density gives a more accurate representation of soil structure and its impact on plant growth.
Difference between bulk density and true density?
Bulk density refers to the mass of a material per unit volume including the voids present, while true density refers to the mass of a material per unit volume excluding any voids or pores. Bulk density is typically lower than true density due to the inclusion of void spaces. True density gives a more accurate measure of the material's mass per unit volume.
What are factors that affect bulk density?
Factors that affect bulk density include particle size, shape, and compaction, moisture content, and the arrangement of particles within a given volume. Additionally, the nature and density of the material itself, as well as the presence of air gaps or pores, can influence bulk density.
What is the bulk density of perspex?
The bulk density of perspex (also known as acrylic) typically ranges from 1.17 to 1.20 grams per cubic centimeter.
What are the differences between soil bulk density and particle density?
Bulk density is the dry mass of the solids (M sub t) / total volume (V sub t) Particle density is bulk density (P sub b) / 1 minus total porosity (1-theta).
What is the difference between bulk motion and diffusion?
The difference between the two is that bulk motion is the flow through the capillary. Diffusion is the movement of the molecules in a fluid.Ê
What is the relationship between bulk density and porosity?
Bulk density and porosity have an inverse relationship. As bulk density increases, porosity decreases and vice versa. Bulk density is a measure of the mass of soil per unit volume, while porosity is a measure of the void spaces within the soil.
.what is the loose bulk density of iron ore?
The solid density of iron ore generally lies between 3.35 and 5.6 tonnes per cubic metre, depending on the particular characteristics of the ore being considered. When the ore is broken up, air spaces are formed between the particles of ore, and the "apparent" density will be lower. The loose bulk density is one measure, the compacted bulk density is another, and the fluidised bulk density is yet another. The loose bulk density is measured on a sample of loose ore, that has not been allowed to self-compact over time, and has not been mechanically compacted. It will generally measure between 50% and 60% of the value of the solid density.
How do you calculate volume if given bulk density?
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
How can you demonstrate ther is space between molecules of water?
Calculate volume of molecule, calculate mass of molecule, compare to bulk density. Lower bulk density indicates empty space.
Maximum bulk density can be occur?
bulk density depend on that material from which soil formed. so maximum bulk density depend on particle density of that mineral. Therefore,we can only tapped the soil upto perticle density. so maximum bulk density may be occur at equal to paricle density.
What is bulk density formula for magnatite?
The bulk density of magnetite can be calculated using the formula: Bulk Density = (mass of material) / (volume of material). This formula involves measuring the mass of the magnetite sample and calculating its volume to determine the bulk density.

How does tap density and bulk density differs?
Tap density is the density of a powder when tapped or compacted to minimize void spaces, providing a measure of how closely packed the particles are. Bulk density, on the other hand, is the density of a powder in its loose, unpacked state and includes the void spaces between particles. In general, tap density is higher than bulk density due to the compaction of particles during tapping.
