Automatic installation
======================
NB: for the moment, these release are CoolProp version 4 and not the version 5
you are looking for. See the "Manual installation" section for informations
concerning version 5
Linux and MacOS X
-----------------
Depending on which you prefer, you can run either of the two commands::
sudo easy_install CoolProp
or::
sudo pip install CoolProp
You may need to first install Cython::
sudo easy_install Cython
Special MacOS X requirement
---------------------------
If you never used any command-line installation before, chances are that you
do not have the compiling utilities needed. Thus you need to first install
Xcode: see the description on the page http://guide.macports.org/#installing.xcode
After installing, you need to accept the licence by running the following
command in the Terminal::
xcodebuild -license
and explicitly typing "agree" before closing. Then you can resume to the
former method.
Windows

To be explained...
Manual installation
===================
Special MacOS X requirement
---------------------------
Same advices as the one in the previous section apply: make sure you have
Xcode installed (see the description on the page
http://guide.macports.org/#installing.xcode) and make sure you've run the
command::
xcodebuild -license
and explicitly typing "agree" before closing.
Linux and MacOS X
-----------------
If not already there, you need Cython to be installed::
sudo easy_install Cython
Then, follow the commands::
# Check out the sources for CoolProp
git clone https://github.com/CoolProp/CoolProp --recursive
# Move into the folder you just created
cd CoolProp/wrappers/Python
# Start the installation
sudo python setup.py install
If you would like to install CoolProp just for a given version of Python (for
example if ``python`` links to ``python3.4`` and you also have a ``python2.7``
executable), simply use this version of python to execute the ``setup.py``
script::
sudo python2.7 setup.py install
For Pyzo users
--------------
Suppose the directory containing pyzo is on your Desktop in
``~/Desktop/pyzo2014a/``. Then you can install CoolProp to be used within pyzo
by following the same lines as above::
# Check out the sources for CoolProp
git clone https://github.com/CoolProp/CoolProp --recursive
# Move into the folder you just created
cd CoolProp/wrappers/Python
# Start the installation (~/Desktop/pyzo2014a/ to be changed according to
# your effective installation)
sudo ~/Desktop/pyzo2014a/bin/python setup.py install

Usage
=====
Once installed, you can use CoolProp for various things:
* Compute special values in SI units::
import CoolProp.CoolProp as CP
fluid = 'Water'
pressure_at_critical_point = CP.PropsSI(fluid,'pcrit')
# Massic volume (in m^3/kg) is the inverse of density
# (or volumic mass in kg/m^3). Let's compute the massic volume of liquid
# at 1bar (1e5 Pa) of pressure
vL = 1/CP.PropsSI('D','P',1e5,'Q',0,fluid)
# Same for saturated vapor
vG = 1/CP.PropsSI('D','P',1e5,'Q',1,fluid)
* Get some nice graphs::
import CoolProp.Plots as CPP
ph_plot = CPP.PropsPlot('Water','Ph')
ph_plot.savefig('enthalpy_pressure_graph_for_Water.png')
* Solve `thermodynamics exercices`_
* Make you own `more complex graphs`_ if you feel the graphing interface is lacking something
* Make even more complex graphs using `3D stuff`_
