Cubic meters per second (m³/s) is a unit of measurement used to express the flow rate of a fluid. It indicates the volume of fluid that passes through a specific point in a system every second. This measurement is commonly used in fields such as engineering, hydrology, and environmental science to assess water flow in rivers, pipelines, and other systems. For example, when measuring the flow of a river, knowing the cubic meters per second helps determine how much water is moving at any given time. This information is crucial for managing water resources, predicting floods, and designing infrastructure like dams and bridges.
