What are the typical units used to measure flow?

The typical units used to measure flow are often specific to the context, and in this case, "CFS" (Cubic Feet per Second), "GPM" (Gallons per Minute), and "MGD" (Million Gallons per Day) are widely recognized and utilized in various industries, particularly water and wastewater management.

CFS is commonly used in hydrological studies and engineering to quantify water flow in rivers and streams, providing a standard measurement for understanding how much water is moving past a certain point over time. GPM is frequent in domestic and industrial applications, helping to assess the flow rate of systems such as plumbing, irrigation, and water treatment. MGD is particularly relevant in the water treatment sector and environmental management, where it allows for the assessment of large-scale water supply and sewage systems.

While liters and gallons are indeed valid measures of volume, they are not typically used to express flow rate in the same context as the units specified. Similarly, barrels and cubic meters serve as volume measurements rather than flow rates, while ounces and quarts are considerably smaller quantities and less applicable for the measurement of flow in practical scenarios. Therefore, the units in the chosen answer are best suited for accurately describing flow in various contexts related to water management
