Determine the sensitivity due to rate constants for a river with a CBOD waste discharge (Lo=W/Q=22 mg/L) and an initial DO deficit (Do=1.6 mg/L). Plot your results as DO deficit concentration (D) versus travel time (x/u). Give values of Dc and xc in each case. Which case is the right match? a. kd=0.69 day-1 kg=0.92 day-1 b. kd=0.32 day-1 ka=0.92 day-1 c. =0.62 day-1 kq=0.69 day-1 d. kgka=0.92 day-1 e.kpkg=0.62 day-1 Figure 1 t.days Figure 2 1 2 3 t.days Figure 3 10 D.mg/L Uud 3-4 1 2 3 days Figure 4 10 9 8 mul 1 days
