From here density and SG are calculated using the following formulas: Specific Gravity = (Weight A / Weight B)Density = (Weight A / Weight B) * 0.9976 g/cm3 , where 0.9976 g/cm3 is equal to the density of distilled water at 23C. 0000163869 00000 n Specific . Lens Materials In the next blog post, we will explain which of these plastic types can be recycled and which not, so stick around! i.e. Beam Deflections and Stress Fluids Flow Engineering Specific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. Plastics This may also be referred to as relative density. Specific gravity, 0000151051 00000 n 0000149962 00000 n 0000155825 00000 n Feedback Advertising 0000159988 00000 n Calculate Shot Size Vs. Barrel Capacity Specific Gravity The density of water is 1.0 g/mL at room temperature, so the specific gravity is equal to the density of the object expressed without a unit. can be special ordered.
