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 P r = 0.02 to P r = 40, and the temperature extended from T r = 0.265 to T r = 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.
