Steam

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

Use Steam to avoid tedious interpolation of steam properties from printed steam tables.

Select one of the following fuctions:

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

to calculate:

Specific enthalpy
Specific entropy
Specific volume
Isobaric specific heat capacity
Specific internal energy
Density

Select 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.

Select Imperial (Btu, psia, etc.) or Metric (kJ, kPa, etc.) engineering units. You can choose the metric units (e.g., kilopascals, megapascals, bars, etc. for pressure) as desired. Tap the i button to access the metric units setup screen.

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 heat of vaporization (hfg) is calculated for specific enthalpy.
