# # Examples of props
#
# *Density* $\frac{kg}{m^3}$ of **nitrogen** at a *temperature* **25 °C**
# and a *pressure* **1 atmosphere**:
props('D', 'Nitrogen', {T:25 degC, P:1 atm})
# Saturated vapor enthalpy $\frac{J}{kg}$ of **R134a** at **25 °C**
props('H', 'R134a', {T: 25 degC, Q:1})
# # Example of Phase
#
# *Phase* of **water** at a *pressure* of **1 atmosphere** and **0%** *Quality*:
phase('Water', {P:1 atm, Q: 0 %})
# # Examples of HAprops
#
# * *Enthalpy* $\frac{J}{{kg}_{dry\ air}}$ as a function of *temperature*, *pressure* and *relative humidity* at STP
h = HAprops('H', {T: 25 degC, P:1 atm, R:50 %})
# * *Temperature* of **saturated air** at the previous *enthalpy*
