If the fluid you are using in the pipe system does not exist in the Pipe Flow Expert fluid database, you can quickly add the fluid to the database by clicking the Add new fluid data button on the Fluid data screen.


NOTE: Be sure to enter the value for the fluid’s properties in the units displayed on the column header. For example, if you are using imperial units, ºF for Fahrenheit is displayed under Temperature in the Temperature column. The temperature value in this case should be entered in degrees Fahrenheit.

  1. Type the fluid’s viscosity centipoise in the Viscosity Centipoise field.


  1. Type the fluid’s vapor pressure in the Vapour Press field.


  1. If the fluid’s state is gas, select the Gas check box in the State field.


  1. Leave the Gas check box blank if the fluid’s state is liquid.


  1. Click Save to save the new fluid data to the fluid database.


If the current system contains fluids that do not exist in the Fluid Database, the Unknown Fluid Data information panel is displayed on the Fluid Data screen.  To commence the importing of fluid data from the current system, click the Import Fluid Data > From Current System on the Fluid Data Screen or select Tools > Import Fluid Data From Current System on the main menu.  

See Section: Fluid Data Import > Importing Fluid Data from Current System for further information.

Fluid data can also be added to the Fluid Database by importing it from the active system or from fluid data files on disk.  See Section: System Amendments and Group Updates > Fluid Data Import for further information.
