Step 1 — Identity-Giving Function
Function class: FluidConductionFunction
Process class: FluidConductionProcess
Step 2 — Genus Proximus
Genus: Pipe
BFO root: MaterialArtifact
Step 3 — Differentia Specifica
Axiom expression:
∃hasPart.InletEnd ⊓ ∃hasPart.OutletEnd ⊓ ∃hasProperty.DifferentNominalPipeSizes
Step 4 — Necessary Parts
Step 5 — Process Participation Signature
Inputs: {'type': 'PortionOfFluid', 'count': 1, 'constraints': 'at larger or smaller pipe size'}
Outputs: {'type': 'PortionOfFluid', 'count': 1, 'constraints': 'at correspondingly different pipe size, same fluid properties'}
Transformation: geometric transition - changes flow cross-sectional area but preserves fluid composition

Status: exported
Axiom mode: necessary
