👉 A broad fluid refers to a wide range of substances that can flow easily and adapt to various conditions, encompassing liquids, gases, and sometimes semi-solid materials like mud or slurry. These fluids are characterized by their ability to change volume and shape in response to external forces, temperature, pressure, or chemical composition. They play crucial roles in numerous natural processes, such as weathering, erosion, and biological functions, and are also integral to many industrial applications, including manufacturing, transportation, and energy production. Examples include water, air, oil, and various chemical solutions. The term "broad" emphasizes their versatility and adaptability across different environments and applications, highlighting their fundamental importance in both natural and engineered systems.
