The reduction in fluid pressure that results when a fluid flows through a constricted section of a pipe.
The Venturi effect is a phenomenon in fluid dynamics where a fluid's velocity increases and its pressure decreases as it flows through a constricted section of a pipe or channel. This effect is named after the Italian physicist Giovanni Battista Venturi, who first observed it in the 18th century.
Principle[edit]
The Venturi effect is a direct consequence of the Bernoulli's principle, which states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. When a fluid enters a constricted section of a pipe, its velocity must increase to maintain the continuity of flow, leading to a drop in pressure.
Applications[edit]
The Venturi effect has numerous applications in various fields:
- Aviation: Venturi tubes are used in aircraft to measure airspeed and to provide vacuum for gyroscopic instruments.
- Medicine: Venturi masks are used to deliver a precise concentration of oxygen to patients.
- Industrial: Venturi scrubbers are used to remove particles from industrial exhaust streams.
Venturi tube[edit]
A Venturi tube is a device that utilizes the Venturi effect to measure the flow rate of a fluid. It consists of a tube with a constricted throat that causes a pressure drop, which can be measured to determine the flow rate.
