Mass conservation

Definition

Mass conservation is a fundamental principle stating that mass cannot be created or destroyed in an isolated system. This principle plays a critical role in understanding the flow and behavior of fluids, ensuring that the mass entering a system equals the mass exiting it, which is essential for analyzing various processes in fluid dynamics.
