Abstract : Using a particular set of interaction parameters, it is shown that the viscosity of dissociated hightemperature air is well represented by a simple formula which is a perturbation from the puremolecule result. To this order, information about atomatom interactions is not needed. The perturbation formula is then used to show that there is no point in calculating the effect of composition on viscosity unless the atommolecule interaction parameters are known within a very few per cent. Finally, it is noted that the composition effect on boundarylayer transport properties stems chiefly from the dilatation factor in the state equation, tending to justify calculation of viscosity on a puremolecule basis.
