About Long hundredweights per day
The long hundredweight per day (cwt/d, UK) equals 50.80234544/86400 ≈ 5.880×10⁻⁴ kg/s, encountered in legacy British industrial reports for colliery output, port-handling capacity, and sugar-refinery throughput. Historical British coal-mine productivity was routinely expressed in long cwt per miner per day. 1 long cwt/d ≈ 5.880×10⁻⁴ kg/s = 112 lb/d.
About Pounds per minute
The pound per minute (lb/min) equals 0.45359237/60 ≈ 7.560×10⁻³ kg/s, the standard unit for US fire-suppression system design (sprinkler flow demand) and HVAC hydronic loop balancing. A fire-sprinkler head at 15 psi discharges roughly 30-40 lb/min of water; industrial humidifiers are rated in lb/min of steam. 1 lb/min ≈ 7.560×10⁻³ kg/s = 60 lb/h.
