👉 In the context of fluid dynamics, the other fluid typically refers to a gas, which is distinct from liquids in terms of its behavior and properties. While liquids maintain a constant shape and flow smoothly over surfaces, gases expand to fill any container they occupy and can move freely due to the random motion of their molecules. Gases also exhibit compressibility, meaning their density can change with pressure and temperature, unlike liquids which are nearly incompressible. This difference in behavior is crucial in various applications, from weather patterns to industrial processes involving air and other gases.
