The 16 pages that link to Venturi effect, each with the reason it gives.
ManometerRelated: Manometers can measure the pressure change across a Venturi tube to assess flow.
Mass flow rateRelated: The associated pressure difference can be used to infer flow rate.
Bunsen burnerRelated: Gas flow through the burner draws air into its mixing tube.
Steady flowRelated: Steady-flow relations explain its use in flow measurement and fluid transport.
Cubic metre per secondRelated: Venturi meters infer flow rate from pressure differences.
BlowtorchRelated: Many blowtorches use a fast fuel jet to draw air into the burner.
