Bulk density is a measure of mass per unit volume of rock and may be expressed, for example, as metric tonnes per cubic meter (t/m3) or pounds per cubic foot (lbs/cu ft). …
Details
Bulk density is a measure of the mass of a soil per given volume (i.e. g/cm3 ), including solids and pore spaces. Bulk density is a commonly measured soil property by agriculturalists and engineers. High bulk density soils are soils with little pore space, so water infiltration is reduced, root penetration is inhibited, and aeration is ...

Figure 4 – Bulk density test results for six iron ores tested with different methods. In order to indicate possible effects of scalping on compressibility, Figure 5 shows the results for a sample of bauxite tested both with the small cell in the -4mm size fraction and the large bulk density tester with the full-size material for two moisture contents.

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/cu.ft.

Structural Damage due to High Density Cargoes High density cargoes have a greater weight than their volume may imply. Lighter cargoes occupy more space. For example, the stowage factor for corn is 1.42 m3/tonne while for iron ore, the stowage factor can be as small as 0.24 m3/tonne. Tanktop strength is provided in the ship's stability booklet .

The same excavation in feet: Excavated area is 200 feet long 20 feet wide and 2 feet deep with a listed swell of 40% for the material. Bank volume = 200 * 20 * 2 = 8000 ft³. Convert 8000 ft³ to yd³ = 8000/27 = 296 yd³. Loose volume = 296 * 1.4 = 414 yd³. (Calculations are based on the material being of similar consistency.

In some instances, such as iron ore deposits, it is necessary to determine the relationship between the haematite/magnetite and the bulk density as the iron content is the major component of the rock (> 50%). A regression curve may be used to determine the relationship . A similar approach is frequently applied between ash content and density ...
