A Modified Capillary Viscometer for Dynamic Viscosity Measurements: Preliminary Results for Octane and Nonane Up to 30 Mpa and 353 K

In this work, results of dynamic viscosities measurements for Octane and Nonane are presented. The viscosity have been measured with a modified capillary viscometer designed and built to operate at pressures up to 40 MPa and temperatures up to 473.15 K. The dynamic viscosity was measured at pressures up to 30 MPa and temperatures up to 353 K. The total uncertainties of the dynamic viscosity measurements were estimated to be less than 1%. The measured dynamic viscosities were compared with data, predictions and correlations previously reported in the literature, where the differences between the literature and the measurements reported here are less than 0.5%.
