Abstract
This paper presents a survey of the thermodynamic properties of normal hydrogen and parahydrogen with comparisons of properties calculated using the standard models to available experimental data. Motivated by the fact that the currently accepted standards for the thermodynamic properties of hydrogen were based on experimental and correlation work completed before the mid 1980s, we provide an assessment of the accuracy of property values for new system analysis and design at high and low temperatures and pressures. Property values measured and published after the completion of the current standards for both normal hydrogen and parahydrogen are included in the comparisons. Recommendations for new experimental data needed and for new thermodynamic property formulations for normal hydrogen and parahydrogen are included.Citation
