Convert US quarts per minute to US barrels per hour
Convert US quarts per minute (qt/min) to US barrels per hour (bbl/h) instantly and accurately.
Conversion Formula
bbl/h = qt/min × 0.3571428571
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 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.
