Abstract
The present work aims to determine thermo-physical properties such as mass density, specific heat capacity, viscosity, enthalpy and thermal conductivity of argon at cryogenic temperatures and high pressures up to 20 MPa. The deviations from the ideal gas law led to development of many empirical models based on equation of state (EOS) such as van der Waals EOS, Benedict-Webb-Rubin (BWR) EOS, Peng-Robinson EOS, Soave-Redlich- Kwong, etc. to predict the properties of pure substances. The present paper describes the development of a simple computer program in MATLAB for prediction of the properties using Modified Benedict-Webb-Rubin (MBWR) equation of state.
