Engineered Software, Inc. (ESI) provides software for hydraulic analysis, piping system design and pump selection. ESI's software requires input of fluid properties such as density, viscosity, vapor pressure, etc. These values are provided to ESI's software in the form of a 'Fluid Table'.
The following window displays an example Fluid Table. The file is a tab separated values (TSV) file. The application also generates a ".xlog" log file that details the sources and procedures used to generate the exported physical property values.
The ESI Export Dialog enables you to selecting the fluid to export, the output file's name, the phases to export, and the temperature limits of the exported equations.
|Find Button: enables you to enter the chemical whose properties will be exported.
|Browse Button: enables you to select the name of the file which will contain the exported values.
|Phases Controls: options for selecting to export either liquid phase property values, vapor phase property values or both.
|Temperature Limits Controls: enables you to enter the limits over which physical property values will be compiled and/or estimated. Typically these values correspond to the fluid's melting point, boiling point and critical temperature. Usint the Limits button will help in assigning these values.
|Limits Button: activates the Fluid Limits dialog. This dialog will display the fluid's melting point, boiling point, critical temperature and critical pressure. Pressing the dialog's "Assign" button will assign these values as the fluid's temperature limits.
|Export Button: instructs the application to compile data and estimates, regress equation parameters and write these values into the named file.
The following fluid data tables were generated by Cranium and Synapse.
|A Fluid Data Table containing data for both the liquid and vapor phases of ethanol
|A Fluid Data Table containing data for only the vapor phase of ethylene.
|A Fluid Data Table containing data for only the liquid phase of 1,2-propylene glycol.
