  1. Density

    The mass density or density of a material is its mass per unit volume. The symbol most often used for density is ρ. Mathematically, density is defined as mass divided by volume: where ρ is the density, m is the mass, and V is the volume. In some cases, density is also defined as its weight per unit volume, although this quantity is more properly called specific weight. Different materials usually have different densities, and density may be relevant to buoyancy, purity and packaging. Osmium and iridium are the densest known elements at standard conditions for temperature and pressure but certain chemical compounds may be denser. Less dense fluids float on more dense fluids if they do not mix. This concept can be extended, with some care, to less dense solids floating on more dense fluids. If the average density of an object is less than water it will float in water and if it is more than water it will sink in water. Density is sometimes expressed by the dimensionless quantity "specific gravity" or "relative density", i.e. the ratio of the density of the material to that of a standard material, usually water. Thus a specific gravity less than one means that the substance floats in water.

    The density or specific gravity of gunpowder is one of its most important properties. In the form of dust, the velocity of combustion increases rapidly with the density up to about 1.60, when it decreases. In grained powder the velocity of combustion decreases as the density increases. For English or American powder this velocity is about four-tenths of an inch per second. For French and most of the continental powders, which are less dense than the English, it is about forty-eight-hundredths of an inch. The excellent preservative qualities of English and American powders are largely due to their high densities,—the standard being about 1.75. A certain degree of density is absolutely essential to grain powder to prevent the inflamed gases from penetrating the pores of the powder and flashing off the whole mass to the destruction of the gun. In the manufacture of powder the density depends, first, upon the amount of trituration to which the ingredients are subjected in the incorporating mill; second, upon the pressure employed to form the cake; and, third, upon the degree of moisture it contains when subjected to these operations, particularly the last. The pressure-gauge is not a reliable measure of the density given to a powder, though a good indication of the hardness, with which density must not be confounded. Dry powder meal offers a great resistance to compression, but becomes very hard,—the work being consumed in consolidating the surface particles. To obtain uniform density a certain amount of moisture is necessary to assist the particles in their movement. As much as 6 per cent. of moisture is used in making prismatic powder.
