Volumetric flow in practice

Flow rate says how much fluid passes per unit time. Pumps and taps are rated in litres per minute or US gallons per minute (1 GPM ≈ 3.79 L/min), industrial systems in m³/h, and ventilation in CFM — cubic feet per minute (1 CFM ≈ 1.7 m³/h).

Everyday anchors

A kitchen tap runs 6–8 L/min, a shower about 10, a garden hose 15–20. A typical bathroom exhaust fan moves 50–110 CFM, and an aquarium filter is sized at 4–5 tank volumes per hour.
