Isentropic data for real hydrogen are calculated in a range of pressures up to 30,000 atmospheres and temperatures up to 3500 deg K. The effects of ionization, excitation, and dissociation are considered negligible because of the relatively low temperatures and high densities involved. The effects of the intermolecular force are accounted for by fitting a virial coefficient equation to low temperature high density experimental data. These calculated data in turn are fitted to an empirical entropic equation of state. This particular equation of state is convenient for describing many thermodynamic processes.
