What is CoolProp?
-----------------

CoolProp is a C++ library that implements:

* :ref:`Pure and pseudo-pure fluid equations of state and transport properties for 122 components <list_of_fluids>`
* :ref:`Mixture properties using high-accuracy Helmholtz energy formulations <mixtures>`
* :ref:`Correlations of properties of incompressible fluids and brines <Pure>`
* :ref:`Computationally efficient tabular interpolation <tabular_interpolation>`
* :ref:`Highest accuracy psychrometric routines <Humid-Air>`
* :ref:`User-friendly interface around the full capabilities of NIST REFPROP <REFPROP>`
* :ref:`Fast IAPWS-IF97 (Industrial Formulation) for Water/Steam <IF97>`
* :ref:`Cubic equations of state (SRK, PR) <cubic_backend>`
* :ref:`PC-SAFT equation of state <pcsaft_backend>`

High-Level Interface Example
----------------------------

In most languages, the code to calculate density ``D`` of Nitrogen at a temperature ``T`` of 298 K and a pressure ``P`` of 101325 Pa is something like::

    rho = PropsSI('D', 'T', 298.15, 'P', 101325, 'Nitrogen')

See more examples of PropsSI usage at :ref:`High-Level interface <high_level_api>` or :ref:`Examples <examples>`
