Continuity and Bernoulli Flow

Why can fluid speed increase in a narrower passage while pressure changes at the same time?

Build the conceptual model first, then test the same idea through the linked scientific representation or tool.

Two different learning journeys: Quick builds one memorable mental model. Deep rebuilds the concept as a structured scientific argument with precision, mathematics, assumptions and connections.

Continuity enforces mass conservation in the simplified incompressible model, so reducing area increases mean speed when the same volumetric flow rate passes through both sections.
