The specimen is weighed first in air (Weight A), and then weighed when immersed in distilled water at 23C (Weight B). Specific Gravity means specific value of an object under normal temperature and pressure. 0000173991 00000 n For convenience's sake, we have converted the specific gravities provided by the manufacturers of our products to grams per cubic centimeters. We don't save this data. First, we have to know that the formula of density is: As formula shown, density is total mass of the object divided by total volume of object, which means: 1 gram per cubic centimetre or 1 kilogram per cubic metre.Density of water is1 gram per cubic centimeter (1 g/cm3), but actually, the exact density of water is not really 1 g/cm3, but rather a bit less (very, very little less) than 1, so we can say thatgenerally the weight and volume of water is the same.What's the meaning of "Specific Gravity"?Specific Gravity means specific value of an object undernormal temperature and pressure. Videos Design Manufacture Second, polystyrene foam blows in the wind and floats on water, due to its low specific gravity. This may also be referred to as relative density. Polycarbonate 1.2 Available in a range of sizes these trays have many industrial uses. The tests for density and SG are particularly significant in the custom sheet industry because plastic sheet is sold on a cost per pound basis.
