iapws
=====

Python implementation of standard from IAPWS (http://www.iapws.org/release.html). The module implements the full set of standards, including::

    IAPWS-IF97
    IAPWS-95
    IAPWS-06 for Ice
    IAPWS-08 for seawater
    IAPWS-17 for Heavy water
    ...
    

dependences
--------------------

* Support for both python branch::

  * python 2.7
  * python 3.4 or later

* Numpy-scipy: library with mathematic and scientific tools


install
--------------------

In debian you can find in official repositories in jessie, testing and sid. In ubuntu it's in official repositories from ubuntu saucy (13.10). In other system you can install using pip::

	pip install iapws
 
or directly from the github repository::

    pip install git+https://github.com/jjgomera/iapws.git

This is the recommended option to have the latest version.

For a rapid usage demostration, see this examples 


IAPWS-IF97 (`see full documentation <https://iapws.readthedocs.io/en/latest/iapws.iapws97.html#iapws.iapws97.IAPWS97>`__)

.. code:: python

	from iapws import IAPWS97
	sat_steam=IAPWS97(P=1,x=1)                #saturated steam with known P
	sat_liquid=IAPWS97(T=370, x=0)            #saturated liquid with known T
	steam=IAPWS97(P=2.5, T=500)               #steam with known P and T
	print(sat_steam.h, sat_liquid.h, steam.h) #calculated enthalpies
    

IAPWS-95 (`see full documentation <https://iapws.readthedocs.io/en/latest/iapws.iapws95.html#iapws.iapws95.IAPWS95>`__)

.. code:: python

	from iapws import IAPWS95
	sat_steam=IAPWS95(P=1,x=1)                #saturated steam with known P
	sat_liquid=IAPWS95(T=370, x=0)            #saturated liquid with known T
	steam=IAPWS95(P=2.5, T=500)               #steam with known P and T
	print(sat_steam.h, sat_liquid.h, steam.h) #calculated enthalpies
    

IAPWS-17 for Heavy water (`see full documentation <https://iapws.readthedocs.io/en/latest/iapws.iapws95.html#iapws.iapws95.D2O>`__)

.. code:: python

	from iapws import D2O
	sat_liquid=D2O(T=370, x=0)            #saturated liquid with known T
	print(sat_liquid.h)                   #calculated enthalpy


IAPWS-06 for Ice Ih (`see full documentation <https://iapws.readthedocs.io/en/latest/iapws._iapws.html#iapws._iapws._Ice>`__)

.. code:: python

    from iapws import _Ice
    ice=_Ice(273.15, 0.101325)            #Ice at normal melting point
    print(ice["rho"])                     #Calculated density


IAPWS-08 for seawater (`see full documentation <https://iapws.readthedocs.io/en/latest/iapws.iapws08.html#iapws.iapws08.SeaWater>`__)

.. code:: python

    from iapws import SeaWater
    state = SeaWater(T=300, P=0.101325, S=0.001)    #Seawater with 0.1% Salinity
    print(state.cp)                                 # Get cp


TODO
====

* TODO: Improve convergence in two phase region for IAPWS95 and D2O class
* TODO: Implement SBTL method for fast calculation
* TODO: Implement TTSE method for fast calculation

Ammonia-water mixture:

* TODO: Add equilibrium routine

I've tried to test all code and use all values for computer verification the standards give, but anyway the code can have hidden problem.
