Adding elevation loss to Pipe Pressure Drop calculation using source code

[Anonymous]

PipePressureDrop is currently using the length of pipe and friction to calculate pressure loss. However, it does not take into account pressure loss due to elevation. Below is the default method for pressure drop calculation from source code:

Total pressure loss must include pressure loss due to elevation. To do this, we must include the normal offset difference of the pipe segment and multiply that by the pressure drop per elevation offset difference. Below is how the pressure drop would ideally be calculated in source code.






Currently all variables being used for calculations are referencing class Autodesk.Revit.DB.Plumbing.PipePressureDropData.

StartOffset and EndfOffset are referenced in class Autodesk.Revit.DB.Extrusion.




How do we use dDeltaOffset within public void Calculate(PipePressureDropData data)?

Hi, I'm new to this, I'm a student from Bolivia. 
I would like to install this addin UserMepCalculation to revit but I don't know if it could help me by indicating the specific location and what should I change if a video could be made it would be very helpful. greetings and grateful

Hi,

Have you made any progress on this issue?

The critical path should take into account the pressure loss due to the elevation difference.

Up to me the pipes should have a new parameter indicating this pressure loss.
