Revit automatically calculates specific pipe sizing for the systems created in a project.
The following topic provides tables and methods used for calculating size requirements and selecting pipe for systems.

Pipe Sizing and Calculation Methods
Topics in this section
- Fixture Units to Flow (GPM) Conversion
Revit performs a general conversion from fixture units to flow, using the values found in the 2006 International Plumbing Code (IPC), Table E103.3 (3). - Piping System Properties
View and modify the properties for piping systems. - Piping Instance Properties
View and modify the instance properties for piping. - Pipe Sizing Methods
- About Pressure Drop Calculation
Revit computes pressure losses in piping based on the geometry and roughness of piping, fluid density, and fluid dynamic viscosity. - About Pressure Loss through Fittings
Revit uses the Excess Head (K) method to compute the head loss through a fitting. - Pressure Drop Calculation with Analysis Enabled
You can enable background calculations for pressure drop for closed loop hydronic piping networks. - Pipe Sizing Examples
In Revit, you use the Pipe Sizing dialog to specify the method used to automatically size or calculate sections of pipe using friction and/or velocity sizing methods.
