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 hour
The short ton per hour (ton/h, US) equals 907.18474/3600 ≈ 0.25199 kg/s, the standard capacity unit for US aggregate crushers, coal-fired power plants, and pellet mills. ASHRAE steam-boiler size references, cement plant kiln output, and mine-hoist capacity are all quoted in short ton/h. A large gyratory crusher processes 1 000-3 000 short ton/h. 1 short ton/h ≈ 0.25199 kg/s ≈ 0.9072 t/h.
