Calculate the thermodynamic properties of air.
Reference Pressure: Default value of 101325 Pa represents the standard atmospheric pressure (1 atm).
Dry Bulb Temperature: Temperature of air measured by a thermometer freely exposed to the air. This is the temperature that is indicated by an ordinary thermometer.
Relative Humidity: Ratio of partial pressure of moisture to partial pressure of moisture at saturation.
Absolute Humidity: Moisture content of a gas by mass.
Wet Bulb Temperature: Temperature read by a thermometer covered in by a wick wetted with water which moved through air unsaturated with water vapor. At 100 % relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature). At lower humidity the wet-bulb temperature is lower than dry-bulb temperature.
Dew Point Temperature: Temperature at which moisture begins to condense when mixture is cooled.
Vapor Pressure: Pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system.
Specific Volume: Ratio of a substance volume to its mass. It is the reciprocal of density.
Specific Enthalpy: Ratio of a system enthalpy to its mass.
