Bernoulli Flow

How it works

Ideal **horizontal** flow: **A₁v₁ = A₂v₂** (continuity). **Bernoulli:** **P + ½ρv²** is constant along a streamline at constant height. In a **narrow** segment **v** increases, so **static pressure P** **decreases** — the Venturi / airplane-wing effect in a nutshell. The canvas shows **steady** v₁, v₂ and P; **animated dots** only illustrate the flow direction and that parcels move faster where the pipe is narrow (same volume flux, different speed).
