What does the Venturi Effect refer to?

The Venturi Effect refers to a reduction in pressure that occurs when a fluid flows through a constricted passage. This principle is based on the Bernoulli's principle, which states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.

In practical terms, when a fluid enters a narrowing section of pipe, its velocity increases because of the decreased cross-sectional area. As the velocity of the fluid increases, the pressure within that section decreases compared to regions where the fluid is traveling slower. This effect is commonly utilized in various applications, such as in carburetors in internal combustion engines, aspirators, and even in atomizers.

Understanding the Venturi Effect is important in various fields, particularly in fluid dynamics and engineering applications where pressure and flow rate management is critical.
