Steam for iPhone and iPod touch

Steam calculates the thermodynamic properties of water and steam for subcooled (compressed liquid), saturated, superheated, and supercritical conditions.


Five functions are provided for calculation of properties:

  • P,T - pressure and temperature

  • P,h - pressure and specific enthalpy

  • P,s - pressure and specific entropy

  • P,x - pressure and steam quality

  • T,x - temperature and steam quality

You can choose either the IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam (IF97) or The 1967 IFC-Formulation for Industrial Use (IFC-67) for property calculations.

The following properties are calculated:

  • Specific enthalpy

  • Specific entropy

  • Specific volume

  • Isobaric specific heat capacity

  • Specific internal energy

  • Density

For saturated and two-phase calculations, saturated liquid and saturated vapor values are calculated. If appropriate for a particular property, the delta from liquid to vapor is also calculated. For example, the latent heat of vaporization (hfg) is calculated for specific enthalpy.
