Convert Pounds per minute to Short tons per second
Convert Pounds per minute (lb/min) to Short tons per second (ton/s) instantly and accurately.
Conversion Formula
ton/s = lb/min × 8.333333333e-6
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 second
The short ton per second (ton/s, US) equals 907.18474 kg/s, used for the very highest industrial and military throughput rates. The Space Shuttle Main Engine consumed propellant at ≈480 kg/s LOX + 160 kg/s LH2 ≈ 640 kg/s ≈ 0.71 ton/s; a large blast-furnace tap discharges molten iron at 1-3 ton/s. 1 short ton/s = 907.18474 kg/s = 2 000 lb/s.
