Viscosity of Gaseous Nitrous Oxide from 298.15 K to 398.15 K at Pressures up to 25 MPa

Abstract

The viscosity of gaseous nitrous oxide was measured using an oscillating disk viscometer of the Maxwell type from 298.15 K to 398.15 K at pressures up to 25 MPa. The results were fitted to an empirical equation as a function of temperature and density. The Chung and Lee−Thodos correlations were tested to fit the experimental viscosity values.
