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 Short tons per day
The short ton per day (ton/d, US) equals 907.18474/86400 ≈ 0.010499 kg/s, the capacity unit for mid-size mining operations, smelters, and US water-treatment chemical dosing. A small gold mine may process 500-1 000 short ton/d of ore; activated-sludge wastewater plants dose chemicals in short ton/d. 1 short ton/d ≈ 0.010499 kg/s ≈ 2 000 lb/d.
