Discussion of experimental viscosity data

The comparison of the datasets given in Table 6.1 was difficult due to the temperature, pressure, and concentration differences between the measurements. Therefore, a regression analysis based on the schemes discussed in Section 6.3 was employed for the temperature and composition dependence for each isobar. In the analysis that follows, a preliminary comparison is given between the various datasets, aiming to help the reader choose which values to use. It should be stressed, however, that the conclusions derived here are only based on a preliminary comparison, and should be viewed accordingly. Below the discrepancies between different datasets were examined statistically in terms of the absolute 

H20-nCa(N03)2 Two datasets were found (Zeynalova et al., 1991 Abdulagatov et al, 2004). The agreement between these data sets at atmospheric pressure and at temperatures from 298 to 348 K is within 0.1%, while at 373 K 

it seems that the deviations of these datasets are within the quoted mutual uncertainty of each investigator. 

The agreement between the viscosity values reported by Semenyuk et al. (1977a) and the data reported by Pepinov et al. (1986) is within 1%, up to 623 K and 30 MPa. Furthermore, the values reported by Semenyuk et al. (1977a) deviate from the data reported by Kestin et al. (1981a) up to 0.9% at 473 K and 25 mass %, and up to 1.6% at 623 K.
