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.
About Pounds per day
The pound per day (lb/d) equals 0.45359237/86400 ≈ 5.249×10⁻⁶ kg/s, used in wastewater engineering for reporting biochemical oxygen demand (BOD) loads, nutrient loadings, and sludge production. US NPDES permits set effluent mass-load limits in lb/d; a municipal WWTP serving 10 000 people generates roughly 1 500-3 000 lb/d of dry sludge solids. 1 lb/d ≈ 5.249×10⁻⁶ kg/s.
