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.
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.
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.
Bulk density is to find in Wikipedia: http://en.wikipedia.org/wiki/Bulk_density Real density is here to find: http://www.istone.ntua.gr/Training_courses/wp1/real_density.html Apparent density is here to find: http://www.bulk-online.com/Forum/showthread.php?threadid=6440
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.
The bulk density of perspex (also known as acrylic) typically ranges from 1.17 to 1.20 grams per cubic centimeter.
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).
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
A value for porosity can alternatively be calculated from the bulk density ρbulk and particle density ρparticle: Normal particle density is assumed to be approximately 2.65 g/cm3, although a better estimation can be obtained by examining the lithology of the particles.
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
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.
Calculate volume of molecule, calculate mass of molecule, compare to bulk density. Lower bulk density indicates empty space.
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.
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.

"Tapping" is a procedure in which a powder is placed into a graduated cylinder which is then tapped to compress the sample before its volume is measured. This reduces the amount of air trapped in the material. "Theoretical" is a method of determining the density of a mineral from the volume of a single cell.
