(anonymous ftp from nova.cc.purdue.edu) A program to calculate dependent state, thermodynamic, transport, and electrostatic properties of liquid and vapor in the H2O-System as a function of user-specified state conditions and unit and triple point conventions. Covers a range in temperature from circa -20 to 2250 C, and pressure circa 0.01 to 30000 bars; at temperatures less than about 220 bars the phases of ice I through VII bound the retrieval region. Water permits the curious user to the explore temperature, pressure and density space and retrieve corresponding property values or obtain incremental values of user selected properties. NXYPLOT by Jesperson and Pulliam provides support through Services for plotting. This equation of state has a critical point at P=220 bars and T = 374.15 C; a region where vigourous acitivity occurs within the earth's crust. Water 2.0 features the ability to examine H2-O characteristics through multiple parameter increments. Output formats can be user specified and include NXYPlot friendly, NeXTContour friendly, and verbose output. Water 2.0 reports data correctly over the 2-phase surface and provides an elaborate help section. Water 2.0 is compiled under NSOS3.0. The computing engine was written in C by M. Loki Demsey; it was optimized and rewritten from an original FORTRAN engine. James Johnson and Dr. Denis Norton wrote the code and added pieces of pre-written code from, Haar,Gallagher,Kell; NBS/NRC Steam Tables, Hemisphere Publishing Corp,1984, and Levelt, Sengers, et al., 1983. This code and its basis are documented in: Johnson; Subroutine H2O88, Theoretical Geochemistry Software Library, 1988 and in Johnson, and Norton; Critical Phenomena in Hydrothermal..., American Journal of Science,June 1991 Version 2.0, Freeware 1993.
