About Litres per second
The litre per second (L/s) equals 10⁻³ m³/s, the standard unit for municipal water-supply engineering, fire-fighting flows, and HVAC system air handling. A fire hydrant delivers 15-30 L/s; a household mains water connection is typically 0.1-0.5 L/s; a large building HVAC chilled-water loop circulates 50-200 L/s. 1 L/s = 10⁻³ m³/s = 3.6 m³/h ≈ 15.85 US gal/min.
About US quarts per minute
The US quart per minute (qt/min) equals 3.785411784×10⁻³/4/60 ≈ 1.577×10⁻⁵ m³/s, encountered in US small-engine fuel system testing and food-processing pump calibration. Engine dynamometer fuel-flow instrumentation sometimes uses qt/min when testing small gasoline engines consuming 1-6 qt/min at full load. 1 US qt/min ≈ 1.577×10⁻⁵ m³/s.
