The Specific Gas Constant (R) in the context of Exhaust Gas represents a constant value that depends on the composition of the exhaust gases and is used in the ideal gas law equation to calculate various properties of gases, including density.The specific gas constant has different values depending on the specific gas mixture being analyzed.
Its formula and units are as follows:
- R is the specific gas constant in joules per kilogram per kelvin (J/(kg·K)).
- R_universal is the universal gas constant, which is approximately 8.314 joules per mole per kelvin (J/(mol·K)).
- M is the molar mass of the gas mixture in kilograms per mole (kg/mol).
