| Abstract | A web service, http://www.INEELGeoSteam.NET/INEELSteamTables.asmx is developed for the thermodynamic properties of pure water. It uses the SOAP (Simple Object Access Protocol) and is based on the assembly, INEEL.ThermoData.Wtr.dll written in Visual Basic in Visual Studio. The web service calculates 23 properties as a function of temperature (T) and pressure (P) using the IAPWS-95 scientific and IAPWS-IF97 industrial formulations. The interoperability (i.e., independent of programming language, operating system, and platform software) of the web service is illustrated by its use in Excel (i.e., in COM- Component Object Model), in C# (i.e., .NET framework) and a water-heating application in windows platform. It shows that the fluid region is made of compressed liquid and superheated steam and the critical isochor is the separation boundary between them. The water heating vessel program will be extended in future for the geochemical model of geothermal reservoir.sition. |
