Abstract

We present a new wide-ranging correlation for the viscosity of nitrogen based on critically evaluated experimental data. The correlation is designed to be used with densities from an existing equation of state, which is valid from the triple point to 1000 K, at pressures up to 2200 MPa. The estimated uncertainty (at the 95% confidence level) for the viscosity varies depending on the temperature and pressure, from a low of 0.2 % in the dilute-gas range near room temperature, to 4 % for the saturated liquid up to 34 MPa, and maximum of 8 % at pressures above 650 MPa. Extensive comparisons with experimental data are provided.
