Venturi Effect

What is Venturi Effect?

The pressure drop that occurs when a fluid accelerates through a constricted section of pipe. It's a direct consequence of pairing continuity with Bernoulli's principle, exploited whenever a device needs to draw in fluid with no moving parts at all.

The five clues

Engineerdle #50 described Venturi Effect with five clues, revealed one at a time from hardest to most direct. Each clue points at a different property of the concept.

1. 01It relies on a deliberate constriction.
2. 02It's a direct consequence of continuity plus Bernoulli.
3. 03It's used to measure flow rate without any moving parts.
4. 04It's how a paint sprayer and an aspirator draw fluid.
5. 05Named after an 18th-century Italian physicist.
