A new, simple-to-use correlation is developed to predict physical characteristics of pure compounds and petroleum fractions when no experimental data are available on the petroleum fractions. The new correlation is based on available experimental data and uses four coefficients to correlate different variables for predicting petroleum fractions properties. The coefficients are determined numerically by a least-squares approach. The value can be determined by selecting the set of tuned coefficients for a givenproperty. The accuracy of the new correlation can be tested by comparing its average absolute deviation to experimental data reported in Danesh.
