This calculator helps you determine the flow rate of a fluid through a pipe or channel. Flow rate is the volume of fluid that passes through a given cross-sectional area per unit of time. It's a fundamental concept in fluid dynamics and is crucial for various engineering and scientific applications, such as designing pipe systems, managing water resources, and monitoring industrial processes.
