Abstract

The paper presents a detailed study of the effect of pressure on the viscosity of aqueous NaCI solutions in the range 20-150 ΔC and the concentration range 0-5.4 m. The viscosity was measured by the oscillating-disk method in the pressure range 0-30 MPa at six concentrations along a large number of isotherms. The experimental results have an estimated uncertainty of±0.5 %. The results constitute the first measurements of the viscosity of NaCI solutions over an extended range of pressure, temperature, concentration. The experimental data have been correlated in terms of pressure, temperature, concentration. The correlation reproduces the original data to within the quoted uncertainty. The paper includes comparisons between the correlation and the experimental results of other investigators.
