Consider a field inside and outside the ball, i.e. find the ...
Particle density can be determined using specific gravity bottle technique and bulk density by taking soil core samples of known volume in the field and determining the even dry weight (Black et al., 1965a). Water and air movements through soil depends on the pore space and the size distribution of the pores (microPores and macropores).

Bulk density is the weight of soil in a given volume. Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha).
Besides, density is related to the particle size and distribution, and the larger particle size of dietary fiber is associated with lower bulk density . In this study, the ball milling and ultra centrifugal milling partly destroyed the matrix structure of orange peel IDF fraction and thus resulted in smaller particle size.
Inert ceramic balls (ICB) are used as: a. support material beneath catalyst or other granular material. b. hold down material on top of a bed of catalyst or other granular material. c. filler material where a reactive material (e.g., catalyst) is undesirable (e.g., a low flow area . subject to coke formation) d.
bulk = bulk rock volume V matrix = volume of solid particles composing the rock matrix W dry = total dry weight of the rock r matrix = mean density of the matrix minerals. It should be noted that the porosity does not give any information concerning pore sizes, their distribution, and their degree of connectivity.
