👉 A system fluid, often referred to as a working fluid or process fluid, is a substance used within a mechanical system or industrial process to transfer energy, perform work, or facilitate chemical reactions. This fluid can take various forms, such as liquids, gases, or even supercritical fluids, and its properties—like viscosity, density, and thermal conductivity—are crucial for the system's efficiency and performance. System fluids can be pumped, compressed, expanded, or cooled to achieve desired outcomes, such as powering turbines, lubricating moving parts, or facilitating heat exchange. In essence, they act as the medium through which energy and matter are transported and transformed within the system, ensuring smooth operation and optimal functionality.
