We present a wide-ranging correlation expressed in terms of temperature and density for the viscosity of ethanol based on critically evaluated experimental data. The correlation is designed to be used with an existing equation of state from the triple point (159 K) to 620 K and at pressures up to 102 MPa. Comparisons with experimental data indicate the estimated uncertainty of the correlation is 4.2 % (at the 95 % confidence level) for the liquid and supercritical phase at pressures up to 102 MPa, and 2 % in the gas phase. Furthermore, for calculating viscosity values at 0.1 MPa, an additional correlation is proposed, valid from the triple point to the boiling point with an estimated uncertainty of 2.3 % (at the 95 % confidence level).

This paper presents new wide-ranging correlations for the viscosity and thermal conductivity of 1-hexene based on critically evaluated experimental data. The viscosity correlation is valid from the triple point to 580 K and up to 245 MPa pressure, while the thermal conductivity is valid from the triple point to 620 K and 200 MPa pressure. Both correlations are designed to be used with a recently published equation of state that extends from the triple point to 535 K, at pressures up to 245 MPa. The estimated uncertainty (at a 95 % confidence level) for the viscosity is 2 % for the low-density gas (pressures below 0.5 MPa), and 4.8 % over the rest of the range of application. For thermal conductivity, the expanded uncertainty is estimated to be 3 % for the low-density gas and 4 % over the rest of the range.
