Reference correlation of the viscosity of n-Hexadecane from the triple point to 673 K and up to 425 MPa

Abstract

A new correlation for the viscosity of n-hexadecane is presented. The correlation is based upon a body of experimental data that has been critically assessed for internal consistency and for agreement with theory. It is applicable in the temperature range from the triple point to 673 K at pressures up to 425 MPa. The overall uncertainty of the proposed correlation, estimated as the combined expanded uncertainty with a coverage factor of 2, varies from 1% for the viscosity at atmospheric pressure to 10% for the viscosity of the vapor phase at low temperatures. Tables of the viscosity generated by the relevant equations are provided at selected temperatures and pressures and along the saturation line.
