👉 Fluid is a term used in fluid dynamics to describe the state where a fluid's properties, such as velocity and pressure, change smoothly over time without abrupt transitions or discontinuities. This means that the fluid's behavior is continuous and predictable, allowing for the application of fluid dynamics equations to model its movement accurately. In essence, fluid flow is fluid when it exhibits gradual changes in these properties, making it easier to analyze and predict compared to turbulent or chaotic fluid behavior.
