mixprops

Mixture properties calculator.

Installation

Python

pip install mixprops

CLI

Follow instructions from pipx to install pipx.

pipx install git+https://github.com/oaarnikoivu/mixprops.git

Usage

Python

from mixprops.mixture import Mixture
from mixprops.reference_conditions import ReferenceConditions

mixture = Mixture(
    species=[("O2", 0.21), ("N2", 0.79)],
    reference_conditions=ReferenceConditions(
        absolute_pressure_unit="Pa",
        absolute_pressure=101325,
        temperature_unit="C",
        temperature=25
    ))

print(mixture.specific_heat_capacity)
# 1011.338752

CLI

mixprops \
    -rc 101325,25 \
    -u Pa,C \
    -s O2,N2 \
    -sc 0.21,0.79

• rc = Reference conditions -> Absolute pressure,temperature
• u = Reference condition units -> Pressure unit,temperature unit
• s = Comma separated list of species by name or species -> O2,N2 or Oxygen,Nitrogen
• sc = Species molar composition as comma separated mole fractions -> 0.21,0.79

Properties

• molecular_weight - Molecular weight (g/mol)
• density - Density (kg/m3)
• specific_heat_capacity - Specific heat capacity (J/kg-K)
• viscosity - Viscosity (kg/m-s)
• conductivity - Thermal conductivity (W/m-K)
• speed_of_sound - Speed of sound (m/s)
• adiabatic_index - Adiabatic index

Supported species

For the supported species, see the .csv files in the mixprops/data directory.
