Thermophysical Properties of Air

These tables summarize the thermophysical properties of air in the liquid and gaseous states as calculated from the pseudo-pure fluid equation of state of Lemmon et al. (2000). The first table refers to liquid and gaseous air at equilibrium as a function of temperature. The tabulated properties are the bubble-point pressure (i.e., pressure at which boiling begins as the pressure of the liquid is lowered) the dew-point pressure (i.e., pressure at which condensation begins as the pressure of the gas is raised) density (/ ) enthalpy (H) entropy (S) isochoric heat capacity (CJ isobaric heat capacity (C ) speed of sound (u) viscosity (rj) and thermal conductivity (A). The first line of identical temperatures is the bubble-point (liquid) and the second line is the dewpoint (vapor). The normal boiling point of air, i.e., the temperature at which the bubble-point pressure reaches 1 standard atmosphere (1.01325 bar), is 78.90 K (-194.25 °C). [Pg.920]

These values were calculated from the equation of state for dry air (average molecular weight 28.96) treated as a real gas. Values refer to standard atmospheric pressure. The speed of sound varies only slightly with pressure at two atmospheres and -100 °C the value decreases by 0.16%, while at two atmospheres and 80 °C the speed increases by 0.05%. For additional values, see the table in Section 6 labeled Thermophysical Properties of Air. ... [Pg.2310]

Calculated from values of pressure, volume (or density), and temperature in Vasserman, Kazavchinskii, and Rabinovich, Thermophysical Properties of Air and Air Components, Moscow, Nauka, 1966, and NBS-NSF Trans. TT 70-50095,1971 and Vasserman and Rabinovich, Thermophysical Properties of Liquid Air and Its Conv-ponents, Moscow, 1968, and NBS-NSF Trans. 69-55092,1970. [Pg.188]

A humidity chart is not only limited to a specific system of gas and vapor but is also limited to a particular total pressure. The thermophysical properties of air may be generally used with reasonable accuracy for diatomic gases [3], so that charts developed for mixtures in air can be used to describe the properties of the same moisture vapor in a gas such as nitrogen. Charts other than those of moist air are often required in the drying of fine chemicals and pharmaceutical products. These are available in Refs. [3,8,9]. [Pg.10]
