The shear viscosity coefficients of three compressed gaseous and liquid carbon dioxide + ethane mixtures have been measured with a torsional piezoelectric crystal viscometer at temperatures between 210 and 320 K and at pressures to about 30 MPa (4350 psi). The experimental error is estimated to be smaller than 3 percent in most cases. The measurements have been compared with an extended corresponding states model, and used to examine the dependences of the fluidity (reciprocal viscosity) on specific volume, composition and temperature.
