GPSteam is a Steam Properties Calculator scientifically designed to provide a convenient means of obtaining thermodynamic properties of water and steam (English or metric) over a wide range of pressures and temperatures.
Entering any two state conditions (P, T, h, S, Q) in the program returns 10 physical properties of the fluid. The calculator provides a user-selectable “switch” to use either the ASME 1967 IFC or 1997 IAPWS-IFC steam property formulations.
Plus, take advantage of a graphical user interface that displays an active Mollier diagram and enthalpy-drop efficiency calculation for one or more expansion lines. Unit conversions are provided for automatic engineering unit conversions (both English and SI) for user inputs as well as any calculated values.
