Steam Tables and Condenser Performance Calculator

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

BUG report (2/3/2007): The calculator calculates the wrong steam properties when the pressure and temperature inputs to the f(p,t) function are the same value. For example, if you enter 1000 psia and 1000 F and click the f(p,t) button, the calculated steam properties are wrong. To work around the problem, specify inputs that are slightly different, e.g., 1000.0001 psia and 1000 F.

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.

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.
