QuickStart¶
Install EngCoolProp¶
The easiest way to install EngCoolProp is:
pip install engcoolprop
OR on Linux
sudo pip install engcoolprop
OR perhaps
pip install --user engcoolprop
In case of error, see pip Error Messages
Installation From Source¶
Much less common, but if installing from source, then
the best way to install engcoolprop is still pip
.
After navigating to the directory holding EngCoolProp source code, do the following:
cd full/path/to/engcoolprop
pip install -e .
OR on Linux
sudo pip install -e .
OR perhaps
pip install --user -e .
This will execute the local setup.py
file and insure that the pip-specific commands in setup.py
are run.
Running EngCoolProp¶
A simple usage of EngCoolProp is shown here:
# import the package
from engcoolprop.ec_fluid import EC_Fluid
# create a EC_Fluid object (possibly intialize with T and P)
ec = EC_Fluid(symbol="N2", T=530.0,P=100.0 ) # T=degR, P=psia
# set to desired properties
ec.setProps(T=500., D=0.1)
# print a summary of the properties
ec.printProps()
pip Error Messages¶
If you get an error message that pip
is not found, see https://pip.pypa.io/en/latest/installing.html for full description of pip
installation.
There might be issues with pip
failing on Linux with a message like:
InsecurePlatformWarning
or
Cannot fetch index base URL https://pypi.python.org/simple/
Certain Python platforms (specifically, versions of Python earlier than 2.7.9) have the InsecurePlatformWarning. If you encounter this warning, it is strongly recommended you upgrade to a newer Python version, or that you use pyOpenSSL.
Also pip
may be mis-configured and point to the wrong PyPI repository.
You need to fix this global problem with pip
just to make python usable on your system.
If you give up on upgrading python or fixing pip
,
you might also try downloading the engcoolprop source package
(and all dependency source packages)
from PyPI and installing from source as shown above at Installation From Source
