1.The City of Leeds (England) discharges about 1.4 m3/sec to the Aire River. Without the wastewater discharge, the river flow rate would be 12.7 m3/sec. Given that BOD(river) = 3.0 mg/L and BOD(wastewater) = 30.0 mg/L, what is the concentration of BOD in the river-wastewater mix just below the outfall?
2.Compare the monolithic approach, the layered approach, and the microkernel approach in terms of degree of difficulty to debug, portability, efficiency, and degree of structure.
