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.
