Which of the following is a characteristic of turbulent flow?

Turbulent flow is characterized by chaotic and irregular fluid motion. In turbulent flow, the fluid moves in a manner that can form eddies and swirls, leading to a mixing of the fluid and fluctuations in velocity and pressure. This irregularity makes predicting the fluid's behavior at any given point more complex compared to laminar flow, where the fluid particles move in smooth, parallel layers.

Eddies are a key indicator of turbulence, representing localized regions where the fluid rotates in a circular motion, contributing to mixing and energy dissipation. This chaotic nature of turbulent flow can be observed in various real-world scenarios, such as in rivers, the atmosphere, and many engineering applications.
