Water; at a temperature of 73.4’C (23’C) has specific gravity .Specify gravity is important for several reasons.

The reason for the specific gravity being dimensionless is to provide a global consistency between the U.S. and Metric Systems, since various units for density may be used such as pounds per cubic feet or grams per cubic centimeter, etc. Specific gravity varies with temperature and pressure; reference and sample must be compared at the same ...

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. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:

Iron Ores | ispatguru.com. It is a heavy black mineral with metallic luster. Hematite is a steel-gray to iron- black colored mineral which is as hard as magnetite (Moh's scale hardness is 5.5 to 6.5) but slightly less heavy (usually specific gravity varies from 5.0 to 5.3).

How do I calculate specific gravity? To calculate the specific gravity (SG) of an object, you compare the object's density to the density of water: Because the density of water in g/cm 3 is 1.0, the SG of an object is will be almost the same as its density in g/cm 3. However, specific gravity is a unitless number, and is the same in the metric ...
