Engineered Software Export Dialog
Applicability: Cranium, Synapse (core versions 0315+)

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.

Export values into an ESI Fluid File.
  1. Open a Knowledge Base using either Cranium or Synapse.
  2. Click on the File menu and select the Export Values command.
  3. The application will activate the KB Export Dialog.
  4. Select 'ESI Fluid Table Format' from the Output File Format list and press the Export button. The Export to an ESI Fluid Data Table dialog is activated. (See below for documentation.)
  5. Press the Find button. The application will activate a menu giving you the choice of Chemicals or Mixtures.
  6. Select the Chemicals choice. The application will activate the Choose a Chemical dialog. Select acetonitrile.
  7. Press the Browse button to select the file into which the exported values will be written. The extension ".ftbl" will be added if one is not entered.
  8. Select both the Liquid Phase and Vapor Phase options for physical property values.
  9. Press the dialog's Limits button. The application will activate the Fluid Limits dialog. The temperature and pressure limits were retrieved from the current document or estimated if no values were present.
  10. Press the Fluid Limits dialog's Assign button. The application will assign the limits to the export dialog.
  11. Finally press the dialog's Export button. Cranium or Synapse will compile and estimate the required physical properties, regress these properties into equation parameters and write these values and parameters into the named Fluid Data Table.
Export Dialog

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.
Example Files

The following fluid data tables were generated by Cranium and Synapse.
