RESUMO
The well-known formula for calculating the viscosity of hard sphere gases, ηo = 2(mkT)1/2/3π3/2σ2, where σ2 is molecular cross section, is altered to ηo = K(MT)1/2/Vt2/3, where Vt is the molal volume of a liquid that has expanded sufficiently to permit mean free paths long enough to have significant fractions of the random thermal momenta of molecules in free flight and M is molal mass.
