Abstract

A generalized enthalpy-correction chart based on the law of corresponding states was constructed using the compressibility factor information reported by Nelson and Obert(6, 7). The range of pressures covered the region from Pr = 0.02 to Pr = 40, and the temperature extended from Tr = 0.265 to Tr = 12.5. The results produced from the correlation of this work have been found to agree with those obtained from some of the more sophisticated methods already presented in the literature.
