Knowledge of the physical properties of air is necessary in many process engineering processes. For example, in the design of air-cooled heat exchangers, the properties of the media must always be determined as a function of temperature and pressure.
Ranges of validity
Temperature: -150 °C to 1000 °C
Pressure: 1 bar to 1000 bar
Temperature: -212 °C to -142 °C
Boiling pressure: 0.071 bar to 35.992 bar
Dew point pressure: 0.034 bar to 34.964 bar
