What is a characteristic feature of the venturi in a pump system?

In a pump system, the Venturi effect is characterized by a narrow opening that creates low pressure as fluid flows through it. This principle exploits the relationship between the velocity and pressure of a fluid; as the diameter of the pipe decreases at the venturi, the velocity of the fluid increases, leading to a drop in pressure according to Bernoulli's principle. This low pressure created in the venturi can facilitate the movement of fluids within the system or enable the suction of additional fluids or materials.

Understanding this characteristic is crucial for applications where mixing or the introduction of chemicals into a fluid stream is required, often seen in systems like water treatment plants or chemical dosing systems.
