Fluid Mixture From Kay's Rule

Calculate pseudo-critical properties (temperature, pressure, accentric factor, molar mass) of a fluid mixture using the simple form of Kay's rule with no interaction parameters.

The mole fraction of component one is automatically adjusted so that the sum of the mole fractions equals one. The mixture properties are approximate.
