Chapter 1 - Problems 1.A1, 1.B1 and 1.C1

Viscosities of pure gases and gas mixtures, for a wide range of pressures. For pure gases, nowadays we use correlations based on experimental data at different temperatures, covering pressure ranges from 1 atmosphere, or more properly 1.013 bar, to the critical pressure. However, for a narrow range of low pressures the kinetic theory model is accurate enough.
