The fundamental conservation laws—such as the conservation of mass and the first law of thermodynamics—are formulated for a fixed-identity collection of matter, known as a closed system in thermodynamics. However, analyzing a control volume (or open system) is often more practical. This requires converting those fundamental laws into forms applicable to the control volume perspective. A direct analogy exists […]

What Is a Fluid? You will recall from physics that a substance exists in three primary phases: solid, liquid, and gas. (At very high temperatures, it also exists as plasma.) A substance in the liquid or gas phase is referred to as a fluid. Distinction between a solid and a fluid is made on the
