What is flow rate?
Volumetric flow rate is the volume of fluid passing a point per unit of time. Pumps, pipes, faucets, fans and rivers are all rated this way: a kitchen faucet delivers about 6–9 liters per minute, a garden hose about 20–40 L/min, and the Amazon River about 200,000 cubic meters per second.
Plumbing uses liters per minute or gallons per minute (gpm), ventilation uses cubic feet per minute (cfm) or cubic meters per hour, and the oil industry uses barrels per day.
