Venturi effect (Bernoulli’s principle)

principle · 1738 · Early modern era

A flow’s pressure drops where its speed rises.

Where it is used

• Carburettor — is used in. In the throat of the venturi the pressure drops and draws in petrol.
• Lift — is used in. The pressure difference above and below the wing (simply put — Bernoulli).
• Bunsen burner — is used in. Air is drawn in by the jet of gas.
• Pitot tube — is used in. Dynamic pressure (Bernoulli).
• Nebulizer — is used in. Compressor nebulizers use the Venturi effect.
• De Laval nozzle — is used in. The nozzle accelerates the gas.
