About US barrels per hour

The US barrel per hour (bbl/h) equals 0.158987294928/3600 ≈ 4.416×10⁻⁵ m³/s, standard in petroleum-refinery process engineering for crude-oil unit feed rates and product run-downs. Crude-distillation unit (CDU) feed is sized in bbl/h; a 100 000 bbl/d refinery processes ≈4 167 bbl/h. Process simulation software (Aspen HYSYS) uses bbl/h by default for petroleum streams. 1 bbl/h ≈ 4.416×10⁻⁵ 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.
