Every pipeline is an engineered system that bears a fluid transport function and has pipe as a component part at some time.
First-Order Logic TheoryTeoria em Lógica de Primeira Ordem
[Definition]∀x (Pipeline(x) ↔ EngineeredSystem(x) ∧ ∃f (FluidTransportFunction(f) ∧ bearerOf(x,f))) — Steps 1–3: genus + identity-giving function
[Function axiom: FluidTransportFunction]∀f (FluidTransportFunction(f) → ∀p (realizedIn(f,p) → FluidTransportProcess(p)) ∧ ∃p (FluidTransportProcess(p) ∧ realizedIn(f,p))) — Step 1: ∀ preserves type-type identity; ∃ rules out vacuous functions never realised
[Necessary part: Pipe]∀x (Pipeline(x) → ∃p (Pipe(p) ∧ hasComponentPartAtSomeTime(x,p))) — Step 4: mereological commitment — every instance must have this part
[Process participation signature]∀x ∀f ((Pipeline(x) ∧ FluidTransportFunction(f) ∧ bearerOf(x,f)) →
∃m (PortionOfFluid(m) ∧ participatesIn(m,f)) ∧
∃e (PortionOfFluid(e) ∧ participatesIn(e,f)) ∧
processType(f,FluidTransport)) — Step 5: typed participants in the realising process
