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 Short hundredweights per hour
The short hundredweight per hour (cwt/h, US) equals 45.359237/3600 ≈ 0.012600 kg/s. The US short hundredweight (100 lb exactly) is used in grain elevator and feed-mill billing sheets, cotton-gin output metering, and livestock-feed blending operations. A small feed mill might process 100-500 short cwt/h of mixed grain. 1 short cwt/h ≈ 0.012600 kg/s = 100 lb/h.
