About Pounds per second

The pound per second (lb/s) equals 0.45359237 kg/s, widely used in aerospace and large industrial equipment. A Saturn V first-stage engine consumed ≈13 short tons of propellant per second, equal to ≈26 000 lb/s; a typical large centrifugal pump handling water moves ≈500-2000 lb/s at operating flow. 1 lb/s = 0.45359237 kg/s ≈ 3 600 lb/h.

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.
