Function class
FluidConductionFunction ⊑ DesignedFunction

FluidConductionProcess ⊑ PlannedProcess
Like other pipe fittings, the pipe tee's basic function is to conduct fluid while enabling flow division/combining. This is the same generic function as pipes and pipe elbows - it provides a conduit for fluid flow. The T-shape configuration enables branching but the identity-giving function is still fluid conduction.
2 Genus DeterminationDeterminação do Gênero
pipebfo:Object (BFO_0000030)
A pipe tee is fundamentally a specialized form of pipe fitting that provides branching functionality. The source hierarchies suggest 'PIPING COMPONENT' but the most specific appropriate genus from our enriched classes is 'pipe', which captures that this is a fluid conduction artifact. Pipe tees are monolithic artifacts (typically cast or forged as a single piece) without removable subcomponents, making MaterialArtifact the appropriate BFO root rather than Assembly.
3 Differentia SpecificaDiferença Específica
∃hasPartAtAllTimes.BranchPort ⊓ ∃hasPartAtAllTimes.RunPort ⊓ ∃hasPartAtAllTimes.RunPort

Has exactly three ports arranged in T-configuration with one branch port perpendicular to two run ports

The essential structural differentia is the T-shaped geometry with exactly three ports - two run ports (forming the straight-through path) and one branch port perpendicular to the run. This geometric configuration is what distinguishes a pipe tee from other pipe fittings.

The essential parts reflect the T-geometry: three ports (one branch, two run) and the body that houses the flow passages in T-configuration.

InputsEntradas
{'type': 'FluidPortion', 'count': '1-2', 'constraints': 'can enter through run port(s) or branch port'}
OutputsSaídas

TransformationTransformação
flow division or flow combining - no phase change or chemical transformation
A pipe tee can operate in combining mode (two inlets, one outlet) or dividing mode (one inlet, two outlets), enabling fluid distribution or collection without altering the fluid properties.
Disjoint WithDisjunto com
pipe elbow
C1: pipe elbow. Incompatible geometric configurations - T-shaped branching versus curved two-port flow path. Cannot have both three-port T-geometry and two-port curved geometry simultaneously.
