Results Measurements are reported on the compressibility of gaseous propane over the temperature The compressibility data are given in Table 11. The constants of the Beattie- Bridgeman equation of state were determined from the data below the critical density and the constants for propane are given in Table I. The comparison of the pressures computed from the equation with the obrange 96.81 to 275'and from a density of 1.0 to 10.0 moles ...
