Additional Information

Equation of state

The uncertainties of the equation of state are 0.1% in density, 2% in heat capacity, and 1% in the speed of sound, except in the critical region.

Thermal conductivity

The uncertainty in thermal conductivity is 2%.

Viscosity

The uncertainty in viscosity is 2%, except in the dilute gas, where the uncertainty is 0.5%.

Thermal conductivity

The uncertainties in thermal conductivity are 3% in the dilute gas, 4% in the liquid, 5% in the vapor and about 6% elsewhere. In the critical region, the uncertainty is about 18%.

Viscosity

The uncertainties in viscosity are 1.5% in the dilute gas, 4% in the liquid, 5% in the vapor and about 6% elsewhere. In the critical region, the uncertainty is about 12%.

Important Information About This Data

The data above are from an older version of the NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP version 7). We will be updating our site to use the newer version (version 9.1) of this database in the the next couple of months. Information on REFPROP version 9.1 can be found here. REFPROP version 9.1 includes additional data and features not available from this site.
