- Abstract:
- Several computation models for calculating the compressibility factor of high-pressure hydrogen are discussed,including linear equation, Virial Equation, Van der Waals Equation and Redlich and Kwong Equation. ConvertingNIST hydrogen density data to compressibility factor data, the compressibility factor data calculated by the models are compared with NIST data. The computation accuracy of Redlich and Kwong’s Equation is less than 1 % in a wide range of temperature and pressure. The hydrogen compressibility factor data from NIST can be fitted into a linear equation with linear error < 0.55 % when p/T ≥ MPa/K
