4 Νοε 2012 · The Individual Gas Constant depends on the particular gas and is related to the molecular weight of the gas. The value is independent of temperature. The induvidual gas constant, R, for a gas can be calculated from the universal gas constant, R u ( given in several units below ), and the gas molecular weight, M gas :
The gas constant occurs in the ideal gas law: where P is the absolute pressure, V is the volume of gas, n is the amount of substance, m is the mass, and T is the thermodynamic temperature. Rspecific is the mass-specific gas constant. The gas constant is expressed in the same unit as molar heat.

11 Φεβ 2021 · Get the definition and value of the ideal gas constant (R), which is also called the universal gas constant or molar gas constant.
For wet-gas and gas-condensate mixtures, wellstream gravity, w, must be used instead of g 3in Eq. 3.35. Gas density may range from 0.05 lbm/ft3 at standard conditions to 30 lbm/ft3 for high-pressure gases.
