-Two equations of state have been dcvelopcd, one valid over the reduced temperature range 0.2-26 and the other over 0.35-26. Both are intended for use as reference equations of state in the calculation of thcrmodynamic properties via the principle of corresponding states. The equations arc essentially equations of state for methane in that they reproduce the experimentally measured properties of the fluid phase over the whole region for which they exist (reduced temperatures of 0.47 to 3.3) but the extension to higher temperatures was made by utilizing experimental measurements made on nitrogen and hydrogen. An empirical scheme was used for temperatures below 0.47. lNTRoDtJcTloN
