  Venturi - Wikipedia, the free encyclopedia
Venturis are also used to measure the speed of a fluid, by measuring pressure changes from one point to another along the venturi.
Placing a liquid in a U-shaped tube and connecting the ends of the tubes to both ends of a venturi is all that is needed.
Venturi are a more expensive way to measure fluid flow than an orifice plate which uses the same principle as Venturi but is cheaper and less accurate.

The Venturi Effect is the increase in the velocity of a fluid stream as it passes through a constriction in a channel, pipe, or duct.
This application of the Venturi Effect is what causes the thorough mixing of room air in a home that has the Hi-Velocity Systems installed.

 venturi tube --  Britannica Concise Encyclopedia - Your gateway to all Britannica has to offer!
Short pipe with a constricted inner surface, used to measure fluid flows and as a pump.
The effects of constricted channels on fluid flow were first investigated by Giovanni Battista Venturi (1746–1822), but it was Clemens Herschel (1842–1930) who devised the instrument in 1888.
There are countless applications for the principle, including the carburetor, in which air flows through a venturi channel at whose throat gasoline vapour enters through an opening, drawn in by the low pressure.

 venturi tube --  Encyclopædia Britannica
The 18th–19th-century Italian physicist Giovanni Battista Venturi, observing the effects of constricted channels on fluid flow, designed an instrument with a narrow throat in the middle; fluid passing through the tube speeds up as it enters the throat, and the pressure drops.

 Carburetion 101
The next item is the venturi, which is a portion of the carburetor's main air passage that momentarily narrows down.
This was Giovanni Battista Venturi and he found out that if you took a passageway like a tube, and narrowed it down just a bit in the middle, the air flowing through it would have to accelerate momentarily as it went through the narrowed down portion.
But now, because we are varying the size of the venturi, we have to also vary the size of the fuel jet.
