Abstract
Shear viscosities of supercritical carbon dioxide have been measured to 673 K and 8 GPa (80 kbar). Measurements were made in a diamond-anvil cell with a rolling-ball technique. Individual isotherms are well fit by a modified free-volume equation. The data demonstrate a close relation between viscosity and residual entropy.

- In fitting Eq. (1), the EOS of Span and Wagner was preferred as it is correct at lower pressures and, compared with that of Giordano et al., its extrapolation to higher pressures or temperatures is well behaved.
