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.

About UK gallons per second

The UK (imperial) gallon per second (gal/s) equals 4.54609×10⁻³ m³/s, about 20% larger than the US gallon per second. It appears in pre-metric British fire-fighting standards, large pump test certificates, and naval engineering calculations. A UK fire engine pump rated 1 000 UK gal/min delivers ≈16.67 UK gal/s. 1 UK gal/s = 4.54609×10⁻³ m³/s ≈ 1.201 US gal/s.
