fluidprop
=========
Easy access to thermodynamic fluid properties as a function of temperature and
pressure. Comes with a minimal command-line interface for quick inspection.
Provides class ``FluidProperties()`` useful for working out dataseries in your
own scripts.
- Github: https://github.com/Dennis-van-Gils/python-fluidprop
- PyPI: https://pypi.org/project/fluidprop
Installation::
pip install fluidprop
or if you're on macOS or Linux, try::
pip3 install fluidprop
EOS models
----------
Thermodynamic properties are provided by CoolProp, the open-source alternative
to `NIST refprop <https://www.nist.gov/srd/refprop>`_, with most of the calculations relying on the same
equation-of-state (EOS) models as refprop.
* http://www.coolprop.org/
* http://pubs.acs.org/doi/abs/10.1021/ie4033999
Command-line interface
======================
You can run this module from the terminal with::
python -m fluidprop
or if you're on macOS or Linux, try::
python3 -m fluidprop
It will show a minimal command-line interface which guides the user to enter a
fluid, temperature and pressure. It will print out its thermodynamic properties
as a table to the terminal.

FluidProperties()
=================
This class evaluates thermodynamic fluid properties of the given fluid at the
given temperature(s) in ``['C]`` and pressure(s) in ``[bar]``. The results are
stored as properties to this class as ``numpy.ndarray`` arrays. Useful for
working out dataseries.
Example:
.. code-block:: python
from fluidprop import FluidProperties
fluid = FluidProperties("Water", 20, 1)
print(fluid.rho) # [998.2065435]
fluid = FluidProperties("Water", [20, 21, 22], 1)
print(fluid.rho) # [998.2065435 997.99487638 997.77288644]
