Extracted text: 2. A continuous chemical spill is occurring near a pipe that carries the influent water to a reservoir. The pipe has a diameter of 2 m and it opens to a reservoir with a volume of 40 m. The pipe and reservoir behave as a PFR and CMFR respectively with a flow rate of 5 ML/d. The concentration of the chemical in the pipe 50 m away from the entrance to reservoir is determined to be 600 g/L. If the contaminant degrades as first order reaction with a rate constant of 0.01 s, what will be the concentration of the contaminant at the effluent from the reservoir assuming steady state has been achieved?
