WebThe ratio of the molar gas constant (R) to the molar mass (M) of the gas mixture is called The specific gas constant. Denoted by R specific and mathematically expressed as – R s p e c i f c = R M Dimensions Using the ideal gas equation PV = n RT. The gas constant R can be expressed as- R = P V n T Where, P is the pressure. V is the volume, WebThe equation is: ρ = p / RT. Here: ρ is the density of air in kg/cubic meter. p is the absolute pressure in Pa. T is the absolute temperature in K. R is the specific gas constant for dry air in J/ (kg.K) The specific gas constant for dry air is 287.058 J/ (kg.K).
