👉 The operated fluid, also known as the working fluid or process fluid, is a substance that circulates within a system to perform its intended function, typically in mechanical or thermal processes. It is pumped through various components like pumps, valves, and heat exchangers to transfer energy, move materials, or facilitate chemical reactions. In hydraulic systems, it's usually oil under pressure that enables linear or rotational motion, while in heat transfer applications, it could be a liquid or gas that absorbs and distributes thermal energy. The choice of fluid depends on the specific application, considering factors like viscosity, thermal stability, and compatibility with system materials.
