The shear viscosity coefficients of compressed gaseous and liquid nitrogen have been measured with a torsional piezoelectric quartz crystal viscometer at temperatures between 90 and 300 K and at pressures up to 30 MPa (4350 psia). The estimated imprecision and experimental error of the measurements are less than one percent and two percent respectively. The measurements have been compared with other measurements; with a correlating equation, previously proposed for calculating the viscosities of pure compressed gaseous and liquid nitrogen; and with an extended corresponding states model, previously proposed for calculating the viscosities of fluid mixtures. Differences between our measurements, other experimental data, the correlating equation and the extended corresponding states model are discussed.

A complete quantal phase-shift calculation of the transport properties of gaseous H2, D2, HD, and some of their mixtures is presented from 10° to 300°K, based on the Lennard-Jones (12–6) potential. It is found that H2 and D2 have slightly different intermolecular potentials, in agreement with evidence from other sources. Agreement between calculation and experiment is generally good, but there are some small but clear indications that the (12–6) potential model is oversimplified, such as the necessity to use slightly different potantial parameters for the transport properties than for the second virial coefficients.

The coefficient of shear viscosity η of parahydrogen has been measured by the torsional crystal method at temperatures from 14° to 100°K and at pressures up to 345 atm. Twenty compressed fluid isotherms encompass the density range 0.003–0.087 g/cm3 and include the critical region. The precision and accuracy of the measurements is about 0.5%. The temperature dependence of η changes sign at a density approximately twice the critical density. The viscosity at the critical point is estimated to be 35.5±0.5×10−6 g/cm·sec. The viscosity of saturated liquid normal hydrogen is up to 5% greater than that of parahydrogen at the same temperature. Data of this report have been represented within experimental error by an empirical equation of the form η=η0(T)+A(ρ) expB(ρ)/T, where η0(T) is the viscosity in the low-density limit and A(ρ) and B(ρ) are density-dependent coefficients.
