Steam: Tables & Properties
Thermodynamic and Transport
$4.99 · Designed for iPad. Not verified for macOS.
Essential for engineering students trying to match the steam tables in thermodynamics, physics, heat transfer, power cycles, and fluids textbooks.
Now with industrial and scientific steam tables! Fast, accurate, and comprehensive. Steam calculates the thermodynamic and transport properties of water and steam for subcooled, saturated, two-phase, superheated, and supercritical conditions. Steam is the tool you need if you're an engineer working with modern or legacy heat balances, or engineering students in thermodynamics, heat transfer, power cycles, and fluids classes.
Three formulations are included for property calculations:
- IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam (IF97)
- IAPWS Formulation 1995 for the Thermodynamic Properties of Ordinary Water Substance for General and Scientific Use (SF95)
- 1967 IFC-Formulation for Industrial Use (IFC-67)
Switch instantly between imperial (psia, F, Btu/lbm, etc.) or metric (kPa, C, kJ/kg, etc.) engineering units. Customize those sets of units for your needs. With just one tap, convert calculated outputs from one set of units to the other. A third set of units can be defined, and a units conversion calculator is also provided.
Save calculations to review later or to compare differences between the formulations.
On the settings tab, change the number of significant digits in the output, customize the engineering units, modify the font size, and select the theme for the app.
