👉 A continuous fluid, often referred to as a liquid or a non-Newtonian fluid, is a substance that flows smoothly and continuously without the distinct separation of layers or the formation of solid structures. Unlike gases, which are compressible and have no volume, or solids, which maintain a fixed shape and volume, fluids exhibit properties that allow them to flow under the influence of external forces. Examples include water, oil, and blood. These fluids can change their viscosity (thickness or flowability) depending on the applied stress or force, a characteristic seen in non-Newtonian fluids like ketchup or cornstarch suspensions. This fluidity is fundamental in many natural and industrial processes, from the movement of blood through the circulatory system to the flow of oil in pipelines.
