usgs specific gravity of tin

Solids and Metals - Specific Gravity

1) NTP - Normal Temperature and Pressure - is defined as air at 20 o C (293.15 K, 68°F) and 1 atm ( 101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr) Since specific gravity is the ratio between the density (mass per unit volume) of the actual gas and the density of air, specific gravity has no dimension.

Water Density - USGS

Jun 06,  · In less dense liquids the hydrometer will float lower, while in more dense liquids it will float higher. Since water is the "standard" by which other liquids are measured, the mark for water is probably labeled as "1.000"; hence, the specific gravity of water at about 4°C is 1.000.

Specific Gravity of Gases

Specific Weight is defined as weight per unit volume. Weight is a force. The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. The specific gravity of some common gases can be found in the table below: . As a reference, normal air has a specific gravity of 1.

For example, beryllium has a specific gravity (sg) of 1.84 (1840 kg/m³). As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/ft³ (pounds per cubic foot) and if we know that a sample of aluminum has a sg of 2.5 then we can calculate that its density is 2.5 x 62.4 = 156 lbs/ft³.
