Compressibility Date for Helium Over the Temperature Range--5 Deg. to 80 Deg. C and At Pressures to 800 Atmospheres.
NTIS: PB 190 772 :39 pages
Twenty-two compressibility runs were made with helium over the temperature range -5 deg. to 80 deg. C and at pressures to 800 atmospheres. A burnett apparatus was used. Data from the runs were fitted to a fourth degree polynomial equation of state in the pressure and a weighting factor of pr-3/4 was used. All data for a particular isotherm were treated simultaneously. A temperature function was found to represent the parameters b and c. Compressibility factors determined by this investigation are believed to be accurate to better than 0.05 percent.
