The Reynolds Transport Theorem (Section 4-5, Ç engel and Cimbala) Recall from Thermodynamics: A system is a quantity of matter of fixed identity. No mass can cross a system boundary . A control volume is a region in space chosen for study. Mass can cross a control surface (the surface of the control volume). The fundamental conservation laws (conservation of mass, energy, and momentum) apply directly to systems . However, in most fluid mechanics problems, control volume analysis is preferred over system analysis (for the same reason that the Eulerian description is usually preferred over the Lagrangian description). Therefore, we need to transform the conservation laws from a system to a control volume . This is accomplished with the Reynolds transport theorem ( RTT ). There is a direct analogy between the transformation from Lagrangian to Eulerian descriptions (for differential analysis using infinitesimally small fluid elements) and the
