2. Liquids at atmospheric pressure

Viscosity measurements have been carried out for a number of inorganic compounds. When several data sources exist for a given compound, in order to select the most reliable data, criteria that take into account purity, which is the main error, temperature control, corrections applied to the data, data consistency, viscometer calibration, the fact that dynamic viscosity was calculated from kinematic viscosity and consideration of the accuracy of density measurement were used.

However, for many compounds, there is only one source of data. To correlate the data within the temperature range defined for each compound in column 11 of Table 1 , the following equation was used:

η=exp(A+DCT)
