Find the specific gravity of natural gas and other common gases at NTP (normal temperature and pressure). The specific gravity of natural gas is typically 0.60 to 0.70, while the density of air is 1.205 kg/m3.
23 Ιουν 2024 · Learn how to calculate the specific gravity and other properties of natural gas mixtures using different methods and equations. See examples, charts, and references for gas composition, density, viscosity, compressibility, and z factor.
23 Ιουν 2024 · This web page covers the physical and chemical properties of natural gas, such as phase behavior, PVT behavior, gas density, viscosity, and equations of state. It does not mention the specific gravity of natural gas or how to measure it.
23 Ιουν 2024 · Specific gravity of a gas is the ratio of its density to the density of air at standard conditions. It is also equal to the ratio of its molecular weight to the molecular weight of air (28.967).
Learn how to calculate the gas formation volume factor, B g, and the gas viscosity, μ g, for natural gases using the Real Gas Law and the Standing-Katz correlation. Find out how the gas gravity, MW g, and the inorganic impurities, CO 2 and H 2 S, affect the z-factor and the B g.
Specific gravity is defined as the ratio of fluid density to the density of a reference substance, both defined at the same pressure and temperature. These densities are usually defined at standard conditions (14.7 psia and 60°F).
Gas-specific gravity (γ g) is defined as the ratio of the apparent molecular weight of a natural gas to that of air, itself a mixture of gases. The molecular weight of air is usually taken as equal to 28.97 (approximately 79% nitrogen and 21% oxygen).
