In addition to the equation of state for standard air, a mixture model explicit in Helmholtz energy has been developed which is capable of calculating the thermodynamic properties of mixtures containing nitrogen, argon, and oxygen.
The amount of a pollutant in the air can be given as a fraction or ratio, q. This is the amount (moles) of pollution divided by the total amount (moles) of all constituents in the air. For air quality, the ratios are typically reported in parts per million (ppm).
Thermophysical properties at critical and supercritical pressures. General trends of various properties near the critical and pseudocritical points (Pioro, 2008; Pioro and Duffey, 2007) can be illustrated on a basis of those of water (Figs. 6-9).

The ABL is the most important layer with respect to air pollution. Almost all of the airborne pollutants emitted into the ambient atmosphere are transported and dispersed within the ABL. stability. Stability is the tendency to resist vertical motions or to suppress existing turbulence).
The critical pressure coefficient is shown as a function of critical Mach number. The determination of the critical Mach number corresponding to two different values of incompressible pressure coefficient is illustrated.
