Cv in fluid mechanics
WebMar 21, 2024 · This control volume can be fixed, moving or even deforming. The control volume is a specific geometric entity independent of the flowing fluid. The matter within a control volume may change with time, and the mass may not remain constant. Example of different types of control volume. A)Fixed CV: Flow through a pipe.
