    Difference Between Density and Bulk Density

    2011-7-30 · Bulk Density. Bulk density is a very important characteristic of substances such as powders, granules, and other particles like solid substances. Bulk density is defined as the mass of a bulk material divided by the volume occupied by that material. To understand this concept of bulk density, one must first understand what bulk materials are.

    Direct bulk density measurements can be made only

    Direct bulk density measurements can be made only in good standing ground above the water table. In suitable conditions, a cylinder of the material may be bored out, thus creating a regular cavity with smooth sides. The cavity is filled with a measurable volume of very viscous oil or a quick-setting substance such as plaster of Paris. Water may be used in areas of permafrost.
