👉 The goal of a fluid in a system, particularly in the context of engineering or manufacturing, is to ensure smooth and continuous movement without interruption or obstruction. Fluids, such as liquids or gases, are utilized to transmit energy, facilitate processes, and reduce friction between moving parts. By minimizing resistance and wear, fluids enhance efficiency and longevity of machinery and systems. They also play a crucial role in heat transfer, enabling effective cooling or heating processes. In essence, fluids are vital for achieving seamless operation and optimal performance in various industrial applications.
