👉 A performing fluid, also known as a working fluid or medium, is a substance used to transmit energy, heat, or work in various engineering and scientific applications. It can be a liquid, gas, or even a plasma, depending on the context; for instance, in hydraulic systems, it's typically a liquid like oil or water, while in heat exchangers, it might be a gas such as air or steam. The primary role of the performing fluid is to facilitate the transfer of energy or work between different parts of a system, enabling processes like mechanical work, heat conduction, or fluid flow. Its properties—such as viscosity, density, and thermal conductivity—are crucial in determining the efficiency and performance of the system it's used in.
