The paper presents new experimental measurements of the viscosity of aqueous Na2C03 and K2C03 solutions In the temperature range 20-90 °C and the pressure range 0-30 MPa. The measurements cover the concentration range 0-1.7 m for the first salt and 0-2.5 m for the second and are believed to be accurate to ±1 %. The effect of pressure on the density of these solutions has also been measured. The paper contains correlations of the density and viscosity of Na2C03 and K2C03 In terms of temperature, pressure, and concentration. The correlations reproduce the experimental results to within their quoted accuracy._

This paper presents experimental data of the viscosity of aqueous Na2S04 and K2S04 solutions. The viscosity was measured by the osclllatlng-dlsk method In the pressure range 0-30 MPa and the temperature range 20-90 °C.The measurements cover the concentration range 0-1.1 m for the first salt and 0-0.6 m for the second. The experimental results have an estimated uncertainty of ±1.0%. The effect of pressure on the density of these solutions has also been measured. These measurements constitute the first study of the viscosity and the density of Na2S04 and K2S04 solutions over an extended range of pressure, temperature, and concentration. The viscosity and density data have been correlated In terms of pressure, temperature, and concentration. The correlations reproduce the original data to within the quoted uncertainty. The paper Includes comparisons between our correlations and the experimental results of other Investigators.
