1 Control Volume Approach for Hydrosystems Hydrosystem processes transform the space and time distribution of water in hydrologic nd hydraulic systems The commonality of and hydraulic systems. The commonality of all hydrosystems is the physical laws that define the flow of fluid in these systems. A 5 consistent mechanism for developing these physical laws is the control volume approach .

ollowing the Definition of Fluid Mechanics Following the Definition of Fluid Mechanics A system is a collection of matter of fixed entity (always the same atoms or fluid particles), which may move, flow, and interact with its surroundings. A control volume is a volume in space (a geometric entity, independent of mass) through which fluid may flow. We need to describe the laws governing fluid motion using both system gg g y concepts (consider a given mass of fluid) and control volume concepts (consider a given volume). To do this we need an analytical tool to shift from one representation to the other. The Reynolds Transport Theorem provides this tool.
