Thermodynamic Property Modification

 

The property modification windows are used to access property-specific data for certain thermodynamic methods. These data include:

Usage

From the Thermodynamics - Main Window, select (highlight) the system for which modifications are to be made in the Defined Systems list box.

 

Push the Modify button to transfer to the Thermodynamic System - Modification Window.

 

Push the Enter Data button by the property method for which property-specific data are to be accessed.

 

Note: This button is only made available for methods which have property-specific data options.

 

The Data Items relevant to the selected property method are listed. Push the Enter Data button beside the desired Data Item to access the appropriate modification window. Not all items are available for all property methods.
