Pipe Flow Expert includes a fluid database. The Fluid Properties list displays all of the fluids available in the fluid database for either liquids or gases.  When you are selecting a fluid to be used for the current fluid zone you can select an existing fluid, or enter your own fluid data. Once entered, new fluid data will show up in the list of fluids and can then be used just the same as the standard fluid data.


The Fluid Data can be defined and overwritten in the fluid properties section of the Fluid data screen.


New fluid data can be added to the existing database entries by clicking the Add New Fluid button.
