About Kilograms per second
The kilogram per second (kg/s) is the SI coherent derived unit of mass flow rate relevant across all branches of engineering. Jet turbofan engines pass 100-800 kg/s of air through the core and bypass duct combined; drinking-water intake pipelines for a city of one million people sustain flow rates of 1 000-4 000 kg/s. It is the reference unit in the continuity equation and mass-conservation calculations. 1 kg/s = 3 600 kg/h ≈ 2.205 lb/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.
