What is a venturi tunnel?

The simplest apparatus is a tubular setup known as a Venturi tube or simply a Venturi (plural: "Venturis" or occasionally "Venturies"). Fluid flows through a length of pipe of varying diameter. To avoid undue aerodynamic drag, a Venturi tube typically has an entry cone of 30 degrees and an exit cone of 5 degrees.

Consequently, what is a Venturi used for?

Venturi are used to measure the speed of a fluid, by measuring the pressure changes from one point to another along the venture. A venturi can also be used to inject a liquid or a gas into another liquid. A pump forces the liquid flow through a tube connected to: A short piece of tube connected to the gas source.

Beside above, why does pressure decrease in a Venturi? The pressure increases over the smaller surface area, while the narrow flow then creates a vacuum in the water. The fluid's kinetic energy increases results in a pressure decrease.

Similarly, it is asked, how does a venturi work?

Venturi Principle|How do venturis work. A venturi creates a constriction within a pipe (classically an hourglass shape) that varies the flow characteristics of a fluid (either liquid or gas) travelling through the tube. More commonly, a venturi can use this negative pressure to draw a second fluid into the primary flow

What is a venturi nozzle?

The Venturi nozzle is manufactured as a working meter. The Venturi nozzles are used in measurement of fluid, steam and gas in pressure gradients below critical and in steady flow patterns.
