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.
About Kilograms per hour
The kilogram per hour (kg/h) equals 1/3600 kg/s ≈ 2.778×10⁻⁴ kg/s, the dominant metric unit in the chemical and petrochemical industry for equipment sizing. Distillation column feed rates, reactor throughputs, heat-exchanger duty calculations, and pump datasheets routinely use kg/h. A 500 MW coal-fired power station burns ≈180 000 kg/h of coal. 1 kg/h ≈ 2.778×10⁻⁴ kg/s = 2.205 lb/h.
