THERMODYNAMIC PROPERTIES OF HUMID AIR

Calculate thermodynamic properties of humid air based on the CoolProp thermophysical properties database for pure and pseudo-pure fluids. It is applicable for pressure from 0.01 kPa up to 10 MPa, in a temperature range from -143.15 °C up to 350 °C with a humidity ratio from 0 kg of water up to 10 kg of water per kg of dry air.

1 - Available properties are:
* Dry bulb temperature
* Wet bulb temperature
* Dew point temperature
* Relative humidity
* Humidity ratio
* Mixture volume
* Mixture enthalpy
* Mixture entropy
* Thermal conductivity
* Dynamic viscosity
* Water mole fraction
* Vapor partial pressure
* Compressibility factor

2 - See the state point on psychrometric chart.

3 - Two sets of predefined unit systems (SI and British) plus custom units defined separately for each variable.

4 - Ability to email or text message the calculated properties.
