The Venturi Effect is the reduction in fluid pressure that results when the fluid is constricted through a throat section inside the pipe. As a result of this constriction, the fluid velocity increases as it passes through a smaller cross-sectional area, thus creating a decrease in pressure in accordance with Bernoulli's principle. The ...

The essential upstream pipe length of a venturi tube is 5 to 20 diameters; Venturi tubes exist in sizes up to 72″. A venturi tube can pass 25 to 50% more flow than that of an orifice plate keeping the same drop in pressure. Since the early cost of a venturi tube is quite high, it is mainly engaged on larger flows and in more complicated or ...

The Venturi Tube is a tubular device commonly used to measure fluid flow rates. It is based on a physical principle, the Venturi effect. This effect states that as a fluid passes through a narrow section of a pipe, its velocity increases and its pressure decreases. The design of the Venturi Tube takes advantage of this principle, with a ...

Venturi effect is the reduction in pressure (and increase in speed) that a fluid experiences when it flows through a constricted section of a pipe. We are going to use both the continuity equation and the Bernoulli's equation to explain it. We will assume that all parts of the pipe are at the same height, so there are no variations in potential energy.
