Steam Tables Calculator - Water and Steam Properties

With HEI Condenser Performance Calculator

 

This program calculates water and steam properties using the 1967 IFC Formulation for Industrial Use. Java 1.2 or later is required. If the applet does not appear in a seperate window, then you may need to add Java support to your browser. To install the Java Runtime Environment (JRE), go to Java.com.

The program calculates:

  • Steam and water properties using the 1967 IFC Formulation for Industrial Use, and

  • Condenser performance using the HEI (Heat Exchange Institute) method.




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


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








Calculate Steam and Water Properties

The program calculates condensed liquid and superheated vapor properties as functions of pressure and temperature, pressure and enthalpy, and pressure and entropy. It also calculates saturated and wet steam properties as functions of saturation pressure and quality, and saturation temperature and quality. To calculate properties, enter two values and then click the appropriate button at the lower right side of the screen.

For example, to calculate the properties for steam at 1800 psia and 1000 degrees F, enter the pressure and temperature. Then, click the f(p,t) button.

Saturated and wet steam calculations require input of quality and either saturation pressure or saturation temperature. To calculate saturated vapor properties, enter 1.0 for the quality. To calculate saturated liquid properties, enter 0.0 for the quality. For wet steam calcuations, enter a value of quality between 0.0 and 1.0.

For example, to calculate the saturated vapor properties at 500.0 psia, enter 500.0 for the pressure and 1.0 for the quality. Then, click the f(p,x) button.

The steam properties program supports both U.S. customary engineering units (psia, F, Btu/lbm, etc.) and SI engineering units (kPa, C, kJ/kg, etc.). Select the appropriate units on the menu at the top of the window.

Calculate Condenser Performance

The program calculates condenser performance using the HEI method. It calculates the condenser pressure as a function of condenser cleanliness, and also calculates condenser cleanliness as a function of condenser pressure.

To calculate condenser pressure, enter all the values except the condenser pressure. Then, click the f(cleanliness) button.

To calculate the cleanliness, enter all the values except the cleanliness. Then, click the f(pressure) button.

The program calculates condenser performance using U.S. customary engineering units. SI engineering units are not supported.
