Surface tension of mineral oil fractions

The fact that only the two physical constants, viscosity and density, are necessary to determine the surface tension of mineral oil fractions, enabled Cornelissen, Harva and Waterman21 to construct a diagram with the coordinates log vand da4°. This diagram has been constructed by projecting the surfaces of equal values of the surface tension in the log v-n-d space model on the log v-d coordinate plane. In the diagram lines of equal values of the surface tension (at 20°C) were constructed (Fig. 43).
