The Fluid Density Rule node (the FluidDensityRule sheet in the Piping Specification.xls workbook) defines fluid density based on a defined temperature range. The fluid density is necessary for the software to calculate the fluid weight in a pipe or fitting. For cryogenic liquids and compounds that can change phases, you must define a different fluid code, and thus a different density, for each of the different phases.
Specify the density of the fluid for the temperature range that you specified. Include the units of measurement, for example lbm/ft^3 or kg/m^3, for the density.
Fluid Code (Required)
Type the short description of the fluid code for which you want to define density. The fluid code short descriptions are defined on the AllCodeLists.xls workbook in the FluidCode sheet in the Fluid Code Short Description column.
Temperature From (Required)
Specify the lower temperature bound for which the density applies. Include the temperature unit, for example F or C, when defining this value.
Temperature To (Required)
Specify the upper temperature bound for which the density applies. Include the temperature unit, for example F or C, when defining this value.
