    Charakterystyka zmian ściśliwości roztworów soli NaCl pod wpływem wysokich ciśnień hydrostatycznych
    (Wydawnictwa AGH, 2009) Koszela-Marek, Ewa
    The paper presents results of changes in compressibility of water and salt NaCl solutions of concentrations 5, 10, 20 $g/dm^{3}$ under high hydrostatic pressure from 50 up to 400 MPa in 21 degrees of Celsius. Special apparatus was used by compressibility researches - the high-pressure research position. Compressibility for NaCl water solutions evolved non-linearly. A clear relation appeared between changes in the volume of NaCl solutions, and the size of operating pressure. Reaction is also visible between compressibility and the size of concentration of the researched solution. The biggest change in volume (8.96%) appeared by the solution with the smallest concentration (5 $g/dm^{3}$), under the biggest pressure (400 MPa). The smallest change in volume (1.62%) was noted for solution with the biggest concentration (20 $g/dm^{3}$), under the smallest pressure (50 MPa).
