Abstract

The PVT properties and vapor-pressures of water have been measured in the critical region by using a constant-volume apparatus immersed in the constant-temperature bath with the procedure of varying the sample mass along a prescribed isotherm. Ninety-one PVT and five vapor-pressure measurements along 11 isotherms cover the region of temperatures 643 to 673 K and of pressures 19. 7 to 38. 6 MPa, which corresponds to a density variation from 108 to 618 kg/m**3. Based on these measurements, the critical parameters of water are proposed to be 647. 061 K, 22. 041 MPa and 322. 4 kg/m**3 by the scaling law analysis.
