About Long tons per day
The long ton per day (long ton/d) equals 1 016.0469088/86400 ≈ 0.011760 kg/s, used in legacy British mining reports for daily colliery output and in Naval fuel-consumption logs. Historic British Admiralty fuel expenditure tables for Royal Navy warships used long ton/d for bunker coal or oil consumption at various speeds. 1 long ton/d ≈ 0.011760 kg/s ≈ 1.016 t/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.
