**Confused about venturi tube Physics Forums**

Venturi meter – this is a classic flow measurement device, where water is passed through a narrow throat (throat diameter = 38 mm) in order to induce a higher velocity. Pressure is measured upstream and in the throat, to give the two values corresponding to high and low velocity.... The classical Venturi tube (also known as the Herschel Venturi tube) is used to determine flowrate through a pipe. Differential pressure is the pressure difference between the pressure measured at D and at d. Other devices typically used to determine flowrate are

**The Venturi Tube — Collection of Solved Problems**

…of pressure anemometer is the Venturi tube, which is open at both ends and of larger diameter at the ends than at the middle. Airspeed is determined by measuring the pressure at the constriction in the tube.... As an engineering approximation, volumetric flowrates established by Venturi tubes are calculated using Bernoulli's equation. Bernoulli’s equation is one of the best-known and widely-used equations of elementary fluid mechanics.

**Pressure difference in a Venturi tube engineering - reddit**

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. As the fluid velocity in the throat is increased there is a consequential drop in pressure. Italian scientist Giovanni B Venturi (1746-1822) was the first to observe this phenomenon. how to help a friend who does drugs …of pressure anemometer is the Venturi tube, which is open at both ends and of larger diameter at the ends than at the middle. Airspeed is determined by measuring the pressure at the constriction in the tube.

**Orifice plate calculator pressure drop calculation**

The Venturi flow meter obtains a pressure differential by constricting the flow area and therefore increasing the velocity at the constriction, which creates a lower pressure according to … how to find friends with similar interests on facebook 25/05/2009 · Let p1 and p2 are the pressure along the common axis of the tubes. At any point on the axis it is same in all directions. At any point on the axis it is same in all directions. When the liquid is not flowing, p1 = p2. . p1 and p2 does not depend on the gravitational …

- 1/01/2019 · A venturi tube is a tube or pipe which employs a temporary restriction or narrowing in its length to reduce the pressure and increase the velocity of a fluid or gas passing through it.
- The flow nozzle, like the venturi, has a greater flow capacity than the orifice plate and requires a lower initial investment than a venturi tube, but also provides less pressure recovery (Figure 2-6). A major disadvantage of the nozzle is that it is more difficult to replace than the orifice unless it can be removed as part of a spool section.
