Tilavuustiheys

Tilavuustiheys, often translated as bulk density, is a measure of mass per unit volume. It is used to describe how tightly packed a substance is. Unlike true density, which considers only the solid material, tilavuustiheys includes the volume occupied by pores or air pockets within the substance. Therefore, tilavuustiheys is generally lower than true density.

The calculation of tilavuustiheys involves measuring the mass of a given sample and dividing it by the total volume that sample occupies, including any voids. For example, when measuring the tilavuustiheys of soil, the mass of a soil sample is divided by the volume of the container it fills, which accounts for the soil particles, pore spaces, and any trapped air.

Tilavuustiheys is an important property in various fields. In agriculture and forestry, it helps assess soil quality, aeration, and water retention. In materials science, it is used to characterize powders, aggregates, and other granular materials, influencing their handling, storage, and performance in applications like concrete or insulation. In packaging, it affects how much product can fit into a given container. Variations in tilavuustiheys can indicate differences in particle size, shape, moisture content, and compaction.
