A flow through the tube can be created when one blows into the tube. As air tries to force itself through a small opening, pressure builds. When the opening is large enough, air is forced to push through it.
In the diagram below, you can see how the flow of air in a tube is controlled by the pressure of the surrounding air. The pressure in the center is the same as the outside air pressure, but the inside pressure is much higher.
This is because air has a higher density than water, so it has more room to move around.

How does a Venturi water meter work?
A venturi works by measuring the difference in pressure at two different locations. The slower fluid in the larger pipe has a lower pressure than the fast fluid. This causes the smaller pipe to have a higher pressure, which in turn causes a faster flow of fluid through it.
When the two fluids mix, they create a pressure differential that is measured in pounds per square inch (psi). In this case, a 1,000 psi pipe would have the same flow rate as a 500 psi one, but the higher psi pipes would be able to move more fluid at a given pressure.
What is a Venturi water valve?
In this context, a venturi is a device that converts pressure to energy. It gets narrow, then widens out gradually so as not to stir the water up too much. The flow of water slows down as the passage narrows. Well, if you want to get the most out of your water, you need to make sure that you’re getting the right amount of pressure.
If you don’t have enough pressure, your flow will slow down and you won’t get as much water out as you’d like. The same is true if your pressure is too low, or too high. You’ll end up with a lot less water than you would have otherwise, which is not a good thing.
The best way to figure this out is to use a pressure gauge. A good one will be able to tell you exactly what pressure your tank is at, as well as give you an idea of how long it’s been since the last time you filled it up.
Why does pressure drop 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, and the pressure decreases. “This is the first time we’ve seen this in nature,” said study co-author Dr. Michael J. Smith, an associate professor of civil and environmental engineering at the University of Illinois at Urbana-Champaign.
“It’s exciting because it’s a new way of thinking about how water behaves in a fluid. It opens up a whole new set of questions about the behavior of water in different environments.” The research was funded by the National Science Foundation, the U.S. Army Corps of Engineers and NASA.
What is the Venturi effect simple terms?
In a situation with constant mechanical energy, the velocity of a fluid passing through a constricted area will increase and its static pressure will decrease. The principle of continuity as well as the principle of conserve energy are utilized in the effect. This effect is called the “Venturi Effect” and it is the reason why the sound barrier is so effective at preventing sonic booms.
How does venturi create suction?
Venturi vacuum is caused by a restriction in air pressure that is caused when air or fluid flows through a section of a pipe. The vacuums are generated by using a narrow passageway to move fluids or gases. A vacuum created by the passage of air through an opening in a closed pipe or tube.
What is the advantage and disadvantage of Venturi meter?
Solid particles flow through it because of its smooth construction. It is possible to use it for dirty fluids. It can be installed in any of the directions. It is more accurate than the flow meter.
