I am trying to get results for Duct Pressure drop in Revit MEP.
Can you please share your ideas, as how can I achieve this?
This post has some additional information but is based on the Revit MEP calculation white paper from Autodesk. Revit MEP Duct Sizing calculations
Revit MEP computes pressure losses in ductwork based on the geometry and roughness of the ductwork, air
density, and air viscosity. Values for Air Density and Air Viscosity are specified in the Mechanical Settings.
Roughness is specified in the type properties for duct/duct fitting component families.
This values checks with the Hydraulic Diameter parameter shown in the Properties of the Duct in Revit:
After determining the friction factor, the pressure drop can be calculated:
