SteamTable app for iPhone and iPad

The design and performance monitoring of any steam turbine cycle as well as processes that utilize steam as a medium for heating essentially involve the calculations with the various thermodynamic and transport properties of steam and water. A Steam Table is always a handy tool for any Thermodynamics practitioner. Students undergoing a Mechanical Engineering curriculum cannot escape the tricky calculation of the properties using a hard copy of the Steam Tables.

With the long experience of working in a Steam Turbine Development Center by one of the developers of this product, most of the requirements that arise to a practicing engineer have been incorporated into this application. Students of Mechanical Engineering will certainly find in this tool a great relief from the nitty-gritty ways of finding a property from the regular printed formats. The latest of the IAPWS (International Association for Properties of Water and Steam) formulation IF-97 have been used to generate the various properties. The calculations has been rigorously tested and verified. Some calculations close to the critical values of pressure and temperature may show small deviations. We welcome your feedback and suggestions
