Venturi are used to measure the speed of a fluid, by measuring the pressure changes from one point to another along the venture. We produce it in Italy.
The Venturi effect is the phenomenon that occurs when a fluid that is flowing through a pipe is forced through a narrow section, resulting in a pressure decrease and a velocity increase. The effect is mathematically described through the Bernoulli equation and can be observed in both nature and industry. Many industry applications rely on this effect as they need to be able to predict a fluid’s reaction when flowing through constricted piping.

How does the Venturi Effect Work?
The Venturi effect is similar to a jet effect, which is similar to the feeling one gets when the thumb is placed at the end of a garden hose with the water turned on. The water’s velocity increases when the thumb is placed over the water. The pressure increases over the smaller surface area, however, the narrow flow then creates a vacuum in the water. The fluid’s kinetic energy increase results in a pressure decrease, which the physics laws governing fluid dynamics explain. When the fluid reaches a choked flow point, the mass flow decreases, resulting in a decrease in downstream pressure. Bernoulli’s equation can be used to calculate the theoretical pressure drop in a system that experiences the Venturi effect. The equation is as follows: P/2(V(ending)^2 – V(initial)^2, where P = fluid density. The formula assumes that the fluid being measured cannot be compressed and maintains a consistent density.
