Given the following table that includes mixing zone parameters for a water body, estimate the dissolved oxygen concentration "C" of the water body using the Streeter-Phelps equation provided below the table. Note: All parameters and calculations should be stored in a dictionary. Parameter Mixing Zone Flow, (m/s) 1.25 L, (mg/L) 12.43 D, (mg/L) 3.33 Kd 0.179 Kr 0.286 Csats (mg/L) 9.47 t, (day) 0.926 The Streeter-Phelps equation: C = Csat - kal (e-kat-e-krt) + De-krt) kr-kd
