How to get different pressures of piping system elements using C# Revit API?

[alimoffr]

Hi everyone.

I recently asked question about getting flow, static pressure, pressure loss, total pressure and excess pressure of the section of the hydronic supply/return piping system. But now I understand that I need to get flow, static pressure, pressure loss, total pressure and excess pressure of each Terminal Element  (MechanicalEquipment) of the hydronic supply/return piping systems.

Hydronic supply piping system:

Hydronic return piping system:

Mechanical equipment:

Right now I can get all piping systems and all their terminal elements:

I attached file with hydronic piping systems.

Thank you.

Hi.

You can look at the Revit SDK sample TraverseSystem to determine the non-terminal elements in correct order:

• Simple MEP System Traversal -- http://thebuildingcoder.typepad.com/blog/2013/02/simple-mep-system-traversal.html
• Traversing and Exporting all MEP System Graphs -- http://thebuildingcoder.typepad.com/blog/2016/06/traversing-and-exporting-all-mep-system-graphs.html

To determine the pressure in each element, look at this old pressure drop sample:

• Modeless Pressure Drop Tool -- http://thebuildingcoder.typepad.com/blog/2009/10/modeless-pressure-drop-tool.html

I hope this helps.

Cheers,

Hi Jeremy. Thank you for the answer.

But I still don't know how to get static pressure, total pressure and excess pressure of the Element of the system. I can see all required values for systems sections (not elements) with System Inspector tool:

It will be goot If I can get these values for systems sections and It will be great if I can get these parameters for each Terminal Element separately (not in the context of the section).

Have you installed RevitLookup?

If not, please do so right now and check whether it will show you those values.

It provides a full user interface access to all static properties of all Revit database elements and their relationships obtainable via the Revit API.

You should be able to see the properties you are after there, and that will also tell you how to access them programmatically.

Cheers,

Jeremy

Yes I installed RevitLookup, but I can't find those parameters. Maybe System Inspector tool makes calculations to output all kind of pressures and flow of sections.
