1 Ιουλ 2024 · To calculate the specific gravity of a substance, follow these easy steps: Isolate a known volume of the substance: V. Use a scale to measure the mass of that volume: m. Calculate the density of the substance with the ratio: ρ = m/V. Choose your reference substance and calculate its density: ρ₀ = m₀/V₀.
Specific gravity, ratio of the density of a substance to that of a standard substance. Solids and liquids are often compared with water at 4 C, which has a density of 1.0 kg per liter. Gases are often compared with dry air, having a density of 1.29 grams per liter (1.29 ounces per cubic foot) under standard conditions.
Specific gravity of a liquid is the "ratio of the density of the liquid - to the density of water at 4 o C". Specific gravity of some common liquids and fluids:
Specific gravity measurement. The specific gravity is usually measured using an instrument called a hydrometer. The hydrometer partially submerges in the liquid sample, and the reading on the scale at the air-water junction point is recorded, as illustrated in Fig. 1.7.3.
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. Physicists use 39.2 F (4 C) as the standard, but engineers ordinarily use 60 F.
Specific Gravity - SG - is a dimensionless unit defined for liquids as "the ratio of the density of the substance to the density of water at a specified temperature". For gases the Specific Gravity is related to air. Specific Gravity for common fluids are indicated in the table below.
