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 IFCFormulation for Industrial Use (IFC67) for property calculations.
The following properties are calculated:
For saturated and twophase 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.
