The Venturi Effect is a fluid dynamics principle that describes how the speed of a fluid increases as it passes through a constricted section of a pipe. When the cross-sectional area of the pipe narrows, the fluid must flow faster to maintain the same volume flow rate. This increase in velocity leads to a decrease in pressure in that area. This effect is commonly observed in various applications, such as in carburetors for engines and venturi meters for measuring fluid flow. The Venturi Effect is named after the Italian engineer Giovanni Battista Venturi, who studied this phenomenon in the 18th century.
