Experimental investigation of density and tension of vapour in respect to highly mineralized natural bedded waters
The article contains experimental data on the thermal properties of highly mineralized reservoir waters (concentrations of mineral salts are 11,2; 18,11; 25,77; 32,55 and 48 g/l) within the temperature range of 298,15-598,15 K and the pressure range from saturated vapor up to 40 MPa. Error of experimental data is estimated as ±0,065 %. On the grounds of experimental data an equation is composed aimed at calculating density of poorly studied highly mineralized bedded waters in wide ranges of temperature and pressure. Up to the saturation line the proposed equation describes the experimental data with the error of ±0,03 %. Near this line the error significantly increases.
