Notes:
The available experimental density data for hydrogen have been complied to produce a reduced density correlation for the liquid and gaseous states. This investigation has utilized fifty-seven sources of data, extending from the early studies of Amagat (1880) to the recent contributions of Johnston, Keller, and Friedman (1954).Based on the concept of a reduced density, a correlation for hydrogen has been developed ranging in temperature from the melting point (14°K.) to 3,300°K. and in pressure as high as 2,550 atm. This correlation provides continuity between the liquid and gaseous phases; whereas existing equations of state fail to describe the experimental behavior in the transitional region, particularly near the critical point.Four hundred and eighty-five experimental points covering the entire region were checked to establish the reliability of this correlation, which reproduced the experimental data to within 0.49%.
