👉 An employed fluid, often referred to as a working fluid or process fluid, is a substance used in various industrial and engineering applications to transfer energy, facilitate chemical reactions, or enable mechanical processes. Unlike a free fluid, which exists in motion without external forces acting on it, an employed fluid is typically contained within a system, such as pipes, reactors, or heat exchangers, and is subject to external forces like pressure, temperature, and viscosity. This fluid plays a crucial role in processes ranging from power generation and chemical manufacturing to cooling systems and lubrication, ensuring efficient and controlled operation of the system.
