pitzer_pressure_converter

Introduction

Package for converting thermodynamic properties like osmotic coefficient, activity coefficient, apparent molal enthalpy and apparent molal heat capacity from one pressure (P1) to another pressure (P2) at constant temperature and composition.

Models

converter/model_general.py

Implemented the general pressure converter model of Rogers and Pitzer(1982).

Verifications of properties:

  • osmotic coefficient
  • avtivity coefficient
  • apparent molal enthalpy
  • apparent molar heat capacity

converter/model_archer.py

Implemented the general pressure converter model of Archer(1982).

Verifications of properties:

  • osmotic coefficient
  • avtivity coefficient
  • apparent molal enthalpy
  • apparent molar heat capacity
