Flow rate is a measure of how much fluid passes through a specific point in a given amount of time. It is commonly expressed in units such as liters per second (L/s) or gallons per minute (GPM). Understanding flow rate is essential in various fields, including engineering, plumbing, and environmental science, as it helps determine the efficiency of systems that transport liquids. Factors affecting flow rate include the diameter of the pipe, the viscosity of the fluid, and the pressure driving the flow. For example, in a water supply system, a higher flow rate ensures that more water reaches homes and businesses quickly. Accurate measurement of flow rate is crucial for maintaining optimal performance in these systems.
