3. Particulate matter (PM) from vehicle exhaust is entering a gym through an open window andmixing with air discharged from the air conditioning system. The air conditioning systemdischarges 15 m³/s of air with a low PM concentration of only 0.20 mg/m³. The PMconcentration in the air entering through the window is 4.50 mg/m³. If the mixed air exitingthe gym has a PM concentration of 0.75 mg/m², what is the estimated flow rate of the airentering the window of the gym?

A factory is discharging its wastewater into a slowly moving stream that has a mean velocity of 3 cm/s. The flow rate of the stream is 4 times as that of the wastewater. The ultimate BOD of stream and wastewater are 5 mg/L and 105 mg/L, respectively. And DO of the stream and wastewater are 6 mg/L and 1 mg/L, respectively. The temperatures of the stream and wastewater are 15oC. The deoxygenation rate at 15oC is 0.48 day-1, and the re-aeration rate at 15oC is 0.72 day-1.
