WebThe density (ρ) of a substance is the reciprocal of its specific volume (ν). ρ = m/V = 1/ρ. Specific volume is an intensive variable, whereas volume is an extensive variable. The SI system’s standard unit for specific volumes is cubic meters per kilogram (m 3 /kg). The standard unit in the English system is cubic feet per pound-mass (ft 3 ... WebDensity ( volumetric mass density or specific mass) is the substance's mass per unit of volume. The symbol most often used for density is ρ (the lower case Greek letter rho ), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: [1] where ρ is the density, m is the mass, and V is the volume.

WebSpecific gravity for gases is defined as the ratio of the density of the gas to the density of air at a specified temperature and pressure. The density of air at room temperature is 1.20 kg/m 3. S G = ρ g a s ρ a i r. In the exam, if the … WebApr 8, 2024 · The basic definition of air density is very similar to the general definition of density. It tells us how much does a certain volume of air weigh. We can express it with the following density of air formula: \rho = \mathrm {\frac {mass \ of \ air} {volume}} ρ = volumemass of air film crew logo
