absorptionlib 1.0.12

A package for substance properties for absorption systems

Package Description

This package contains thermophysical property data for the following solutions used in absorption:

• NaOH-water
• LiBr-water
• LiCl-water
• CaCl2-water

Installation and Unsage

pip install absorptionlib

# Import
from absorptionlib import NaOH, LiBr, LiCl, CaCl2

# Example Usage
p = 100000 # [Pa]
x = 0.4    # [%]  = [kgNaOH / kgSolution]
t_sat = NaOH.saturation_temperature(p, x)
print(t_sat)

Quick documentation

Each of the submodules have their own "in-line" documentation, which can be called by the "documentation"-method. Each thermophysical property function has a separate docstring, which can be called by the "explain"-method.

# How to get quick documentation on the modules
NaOH.documentation() # or
LiBr.documentation() # or
LiCl.documentation() # or
CaCl2.documentation()

# How to get quick documentation for functions
NaOH.explain("enthalpy")    # returns docstring for NaOH.enthalpy
LiCl.explain("pTDiagram")   # returns docstring for LiCl.pTDiagram
