This ratio is called the specific gravity.
Specific gravity, (similar to density) has no meaning for a gas, since the density varies with pressure and temperature.
Dry Bulk Specific Gravity does not take into account for anything getting into the permeable or impermeable voids of say a stone by water for instance. Saturated Surface Dry Bulk Specific Gravity takes into account for anything getting into the permeable voids only of say a stone by water. Apparent Specific gravity takes into account for the volume of the impermeable voids and not anything getting into the permeable voids of say a stone by water.
This is called the Specific Gravity of a substance. The density of the material divided by the density of water yields the specific gravity, a specific gravity greater than 1 indicates the substance will sink in water. A specific gravity less than 1 indicates the substance will float in water. Because the units expressed in density cancel each other out specific gravity has no unit dimensions. example: substance 1 has a density of 12 grams per ml water has a density of 1 g/ml then substance 1 has a specific gravity of 12. 12 g/ml / 1 g/ml = 12 *note: for true specific gravity the atmospheric pressure, absolute , and the temperature absolute of both the sample material and the water must be indicated in the calculations as well. ** for gasses the constant or reference medium is air
Aluminum has no specific gravity, at least by the current definition of gravity.
mica has the specific gravity of 2.88
Specific gravity of ppc is 3.15
The specific gravity of acetone is approximately 0.79 at 20°C.
but i think the absolute pressure is P(pressure)/{p(density)*g(gravity)}
Specific Gravity.
The specific gravity of quartz is nearly 2.65.
according to Geology.com the specific gravity of Chalcopyrite's is 4.1 -4.3.
