👉 The source fluid is the initial material from which a fluid, such as a gas or liquid, originates and undergoes transformation through various processes like heating, cooling, or chemical reactions to become the fluid we study in thermodynamics and related fields. This fluid can be anything from water vapor in the atmosphere to hydrocarbons in crude oil, and its properties—such as temperature, pressure, and composition—are crucial for understanding the energy transformations and physical phenomena it undergoes. The source fluid's characteristics set the stage for its behavior in different thermodynamic processes and are fundamental to analyzing energy systems, climate dynamics, and industrial applications.
