ABSTRACT
The paper describes an improved Maxwell type oscillating-disk viscometer. The experimental systemwas calibrated by argon, carbon dioxide, nitrogen, hydrogen and verified by nitrogen. The viscosities of gaseous HFC-161were measured from293 K to 369K at pressures from 0.1MPa up to the saturated vapor pressure. An empirical viscosity equation is proposed to interpolate the present experimental data as a function of density and temperature. The uncertainty of the reported viscosity was estimated to be within 1%.
