Flow Rate Unit Knowledge

Flow Rate Basics

Flow rate (volumetric flow rate) measures the volume of fluid passing through a cross-section per unit time. The SI unit is cubic meters per second (m³/s). Common units include liters per minute (L/min) and gallons per minute (GPM).

Common Flow Rate Conversions

1 m³/s = 1000 L/s = 60,000 L/min = 264.17 gal/min (US) = 35.315 ft³/s. 1 L/min = 0.2642 gal/min. 1 CFM (ft³/min) = 28.317 L/min.

Industrial Applications

Oil production is measured in barrels per day (bbl/d). Large industrial pumps deliver thousands of L/min. Water treatment plants process millions of liters per day. HVAC systems are rated in CFM (cubic feet per minute) for air flow.

Fluid Dynamics

Flow rate Q = velocity × cross-sectional area. Increasing pipe diameter decreases velocity for the same flow rate. The continuity equation states that Q₁A₁ = Q₂A₂ for incompressible flow.
