About Pounds per second
The pound per second (lb/s) equals 0.45359237 kg/s, widely used in aerospace and large industrial equipment. A Saturn V first-stage engine consumed ≈13 short tons of propellant per second, equal to ≈26 000 lb/s; a typical large centrifugal pump handling water moves ≈500-2000 lb/s at operating flow. 1 lb/s = 0.45359237 kg/s ≈ 3 600 lb/h.
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.
