Tabulated values of the dynamic and kinematic viscosity of aqueous sodium chloride solutions have been researched in the academic literature (Kestin et al 1981). The data available covers the temperature range 20-150 °C, the pressure range 0.1-35 MPa and the concentration range 0-6 molal. It is estimated that the accuracy of the tabulated values is ±0.5%.

You are to use data, as required, from the tables in the appendices of the research paper by Kestin et al (1981) to investigate the effect of temperature and concentration on viscosity.

Each student has been assigned an individual* sub-set of 35 data point to work with.

Note:

Concentration values

0, 1, 2, 3, 4, 5, 6 mol/kg.
