1947). Fig. 9.9 shows the comparison plot between the laboratory-measured
data and the two correlations available for saturated oil density. The
comparison shows that the Standing (1947) correlation impressively predicts
the saturated oil density for the oil of Problem 2. The undersaturated oil den-
sity was calculated from the basic equation in the two correlations presented
in the figure.
