Steam and water properties based on the "International Association for Properties of Water and Steam Industrial Formulation 1997 (IAPWS IF-97). A full implementation of the IF-97 standard that provides very accurate steam and water properties in ranges from 0-1000 bar and 0-2000°C for use in process Engineering Industry . Provided thermodynamic properties are:

 - Temperature
 - Pressure
 - Enthalpy
 - Specific volume
 - Density
 - Specific entropy

 - Specific internal energy
 - Specific isobaric heat capacity
 - Specific isochoric heat capacity
 - Speed of sound
 - Viscosity
 - Vapour fraction

All properties can be calculated with the inputs, p and T known, p and h known, h and s known and some with pressure and density known. X Steam are a full implementation of the IF-97 formulation for industrial use including all regions and all backward functions for good calculation speed. The code are speed optimized with pressure and enthalpy as inputs for dynamic simulations.

The code are avalible in the following releases:
