Abstract.Recently an equation of state for the hard disk fluid has been proposed based on a statistical evaluation of molecular kinetic long term computer experiments. We generalize this equation to the case of binary mixtures of hard disk fluids and discuss the quality of the generalization in the light of computer experimental data. As in the case of a pure fluid, Moeschlin pressure estimator is applied revealing the usefulness of the idea of pressure superposition in a certain range of the ratio of disk radii.
