“…From these deviations, we can also conclude that the experimental data are internally consistent to within the estimate experimental uncertainty. Equation (16) Figure 7, we compare the new results with data from the literature [13][14][15][16][17][18][19] at pressures up to 10 MPa as deviations from the correlation of Tariq et al 1 Our results agree well with the majority of the experimental data reported in the literature; however, the data of Rajagapol et al 17 at temperatures below 400 K and those of Grachev et al 19 to constrain the behavior of their correlation in the liquid state at temperatures above 441 K and those data are systematically higher than ours at temperatures above 450 K. Figure 8 compares our new results with data from the literature 13,14,[20][21][22][23][24][25][26][27][28][29] at pressure up to 10 MPa as deviations from the correlation of Huber et al 2,3 At temperatures up to 500 K, our new data agree with the correlation to within about ±1 %, which is the stated uncertainty of the correlation for the saturated liquid. At higher temperatures, the deviations are somewhat dependent upon pressure and span the interval (-3 to -6) %.…”

The viscosities of cyclohexane and decane are reported at temperatures between (303.15 and 598.15) K and at pressures of (0.1, 1, 2, 3 and 4) MPa. The experiments were carried out with a dual-capillary viscometer that measures the ratio of the viscosities at temperature T and pressure p to that at a reference temperature of 298.15 K and the same pressure. Absolute values of the viscosity were then obtained with an expanded relative uncertainties at 95 % confidence of 3.0 % by combining the measured ratios with literature values of the viscosity at the reference temperature.

“…13 As discussed before, 7,9 the average radius of the wire is advantageously determined in a single experimental run at a temperature and pressure where the viscosity and density of a reference fluid are well known. Hence, a single experimental run in forced mode with water near 20°C and 0.1 MPa, which is the primary reference for viscosity, was performed to obtain an effective average radius for the wire sensor.…”

The present article describes a novel vibrating-wire viscometer that has been shown to be able to measure viscosities up to 135 mPa‚s, after calibration against water at 20°C, to provide direct traceability to the primary reference for viscosity. For the purpose of validating the instrument, measurements of the viscosity of some selected fluids, including standard reference liquids with viscosity on the order of 100 mPa‚s at 20°C and 2,2,4-trimethylpentane with a viscosity of about 0.5 mPa‚s at the same temperature, were performed. The results obtained show that the instrument is capable of performing viscosity measurements with an estimated overall uncertainty better than (0.8% over the range of (0.5 to 135) mPa‚s.

“…The correlation of Dymond and Øye [44] was heavily based on the measurements of Dymond [40] and the measurements of Oliveira and Wakeham [33] and Knapstad et al [36]. The present correlation includes measurements of additional investigators (see Table 1).…”

This article summarizes the correlation procedures developed for IUPAC Project 2012-040-1-100 [Reference correlations for the thermal conductivity and viscosity of fluids over extended range of conditions (vapor, liquid and supercritical regions)]. This project is focused on the development of wide-range reference correlations for the thermal conductivity and viscosity of fluids that incorporate as much theoretical knowledge of these properties as possible. The thermal conductivity and viscosity correlations developed here for pure fluids are functions of temperature and density. The best available equations of state for a given fluid are used to calculate the thermodynamic properties required for these correlations, often from measured temperatures and pressures. The correlation methodology developed during this project has been applied to hexane in this report but can be applied to any pure fluid with a reliable equation of state and reliable data for the thermal conductivity and viscosity over a significant range of temperatures and densities.
