In this paper two sets of generalized compressibility charts are presented: One set is based upon critical temperatures and pressures as in the past; the other set is based upon pseudo-reduced co-ordinates obtainable from the Lennard-Jones force potential. In both sets the underlying data are more extensive than those used in constructing older charts since a complete survey of existing pvT data was made. The results of this survey for 30 gases are contained in a Bibliography of 275 items which has been constructed to show the extent of the experimental data by including the ranges of pressure and temperature for each item. Although the charts are intended for engineering computations, the chart for the low-pressure region (pr = 0 to 1), for example, has a deviation of 1 per cent for 26 gases. |
