## What is Steam IF97?

Steam IF97 performs calculations of thermodynamic and transport properties of steam based on the latest IAPWS IF-97 formulation.
Given a combination of two input thermodynamic variables, it calculates 20 thermodynamic and transport properties of steam. The results obtained are suitable for engineering, scientific, academic or industrial use.

-Performs all the calculations implementing the latest mathematical formulations from the IAPWS (International Association for the Properties of Water and Steam), IAPWS-IF97 Industrial formulation (Revision 2007).

The following applies when the application has enabled the Full Range of Variables:

-It allows for 14 different combinations of thermodynamic properties to be entered as input parameters:
Temperature / Pressure
Temperature / Enthalpy
Temperature / Internal Energy
Temperature / Entropy
Temperature / Specific Volume
Pressure / Enthalpy
Pressure / Internal Energy
Pressure / Entropy
Pressure / Specific Volume
Enthalpy / Entropy
Enthalpy / Specific Volume
Internal Energy / Specific Volume
Temperature / Vapor Fraction
Pressure / Vapor Fraction

-Calculations are possible on the full valid region of the IAPWS-IF97 (General Properties) or the two-phase region including saturation states for liquid and vapor (Two-phase Properties).

-Supports input parameters and calculation results in both SI (metric) and I-P (English) system of units. 

-For each combination of input thermodynamic properties, it calculates and provides the user with information about the appropriate input values in the valid range of calculations.

-It calculates 20 Thermodynamic and Transport properties of steam using the above formulation:
Pressure
Temperature
Specific Enthalpy
Specific Entropy
Specific Internal Energy
Specific Volume
Density
Speed of Sound
Dynamic Viscosity
Kinematic Viscosity
Thermal Conductivity
Thermal Diffusivity
Isobaric Heat Capacity
Isochoric Heat Capacity
