US quarts per minute (qt/min)
US barrels per second (bbl/s)

Conversion Formula

bbl/s = qt/min × 9.920634921e-5

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.

About US barrels per second

The US barrel per second (bbl/s) equals 0.158987294928 m³/s, an extremely large flow rate used only for catastrophic spill-rate estimates and very large pipeline surge calculations. The 2010 Deepwater Horizon spill peaked at ≈60 000 bbl/d ≈ 0.000694 bbl/s; major subsea pipeline ruptures may briefly exceed 1 bbl/s during decompression. 1 US bbl/s = 0.158987 m³/s ≈ 158.987 L/s.
