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 Slugs per second
The slug per second (slug/s) equals 14.5939029372 kg/s, derived from the Imperial system where 1 slug = 1 lb·s²/ft ≈ 14.594 kg. The slug is the coherent mass unit in the foot-pound-second system; rocket propulsion engineers using US customary units express mass flow in slug/s. A standard American rocket engine consuming 75 000 lb/s of propellant corresponds to ≈75 000/32.174 ≈ 1 830 slug/s. 1 slug/s = 14.5939029372... kg/s.
