Specific Gravity Of Minerals

The specific gravity of a mineral is its weight compared with some substance taken as a standard. Distilled water is taken as a standard for liquids, air or hydrogen for gases, the weights of bodies being proportional to their masses, therefore the specific gravity of a body is equivalent to its relative density.

Since water has a specific gravity of 1.0, free water in an insulating fluid will migrate to the top or bottom depending on the specific gravity of the fluid. The dielectric breakdown of most insulating fluid is inversely related to the water content, meaning the dielectric strength of the fluid is lowered as its water content increases .
