The specific relationship is the bulk density × 0.6 ≤ excluded volume density ≤ bulk density × 0.8.

apparent bulk density of the charge

relative density of hardened concrete

The true density and/or apparent density of the carrier core for electrophotographic developers can be controlled.

If the density of the filter material is not known, the following densities shall be used

apparent density of a powder before compaction

apparent density of flexible cellular materials

The apparent density of the powder may be greater than about 2.9 g/cm3.

The invention relates to microcellular rigid foams with a matrix consisting of cross-linked duromers, especially of polytriazine resins, and with an apparent density of 20 to 95 % of the density of the compact matrix material.

Mass of the empty pool = Mass of water = Density of water x volume of water

The float is selected with a specific gravity to substantially match the specific gravity of the target material.

The core layer has a specific gravity that is at least 0.1 g/cm3 greater than the specific gravity of the core center.

The core layer has a specific gravity that is at least 0.1 g/cm3 greater than the specific gravity of the core center.

In other measurement systems, the density of water is not 1, so density and specific gravity are different numbers.

The core layer has a specific gravity that is at least 0.1 g/cm3 greater than the specific gravity of the core center.

The second filler (174) has a higher relative density than the matrix material (170).

The first filler (172) has a lower relative density than the matrix material (170).
