Abstract:

For representing the PVT properties of pure water and solutions, sea water in particular, the Tumlirz equation was selected. V V infinity - K sub 1S GammaP sub O K sub 2 S P, where V is the specific volume as a function of pressure P, Salinity S and temperature. For pure water SO and for sea water V infinity, gamma and P sub O are the pure water values. For pure water we have obtained an analytic function which fits the data of Kell and Whalley to approx. 8 ppm from 0-100 and approx. 15 ppm from 100-150 up to 1000 bars. The calculated density maximum is at 4.00 degrees. The form of the equation appears to be useful not only for representing the properties of sea water but for deriving partial molal properties of solutions at low concentrations from high concentration data.
