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.
About Metric tons per day
The metric tonne per day (t/d) equals 1 000/86400 ≈ 0.011574 kg/s, standard in hydrometallurgy, wastewater treatment, and environmental mass-balance reporting. A large copper smelter processes 2 000-3 000 t/d of ore; a modern desalination plant produces 100 000-500 000 t/d of potable water; IPCS industrial emission guidelines use t/d for stack mass rates. 1 t/d ≈ 0.011574 kg/s ≈ 1.102 short ton/d.
