Gas constant for air kg
WebFor one mole, therefore, PV / T = R. The dimensions of the universal gas constant R are energy per degree per mole. In the metre-kilogram-second system, the value of R is … The specific gas constant of a gas or a mixture of gases (Rspecific) is given by the molar gas constant divided by the molar mass (M) of the gas or mixture. Just as the molar gas constant can be related to the Boltzmann constant, so can the specific gas constant by dividing the Boltzmann constant by the molecular mass of the gas. Another important relationship comes from thermodynamics. Mayer's relation relates the specifi…
