About the Flow Rate Converter
Flow rate measures the quantity of fluid (liquid or gas) passing a given point per unit time. Volumetric flow rate (m³/s, L/min, gal/min) is used when density is constant, as in plumbing and hydraulics. Mass flow rate (kg/s) is preferred in thermodynamics and chemical engineering where temperature changes affect fluid density significantly.
