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 Ounces per second

The ounce per second (oz/s) equals 0.028349523125 kg/s, a practical US unit for moderate liquid or solid flow measurements. A garden hose delivering 1.5 US gal/min discharges water at roughly 2.1 oz/s; a small popcorn machine pops roughly 0.5-1 oz/s of popped corn at full rate. 1 oz/s = 0.028349523125 kg/s ≈ 0.0625 lb/s.
