The Rio Grande flowing at 1,100 ft/s has an input from the John T. Hickerson WWTP with a flow of 17 MGD. Before the mixing point, the Rio Grande has a chloride (a conservative substance) concentration of 100 mg/L. The Hickerson WWTP effluent is 200 mg/L. Assume perfect mixing. Find the steady state downstream concentration, Cs, in mg/L. O a. 107.35 mg/L O b. 102.34 mg/L O c. 106.86 mg/L d. 103.19 mg/L O e. 100.00 mg/L

Expert Solution
Step 1

->flow rate of Rio Grande, F1 = 1100 ft3s

since 1 ft3s = 28.3168 Ls

hence, 1100 ft3s = 1100 x 28.3168 = 31148.48 Ls

-> flow rate of  John T. Hickerson wwtp, F2 = 17 MGD

since 1 MGD = 43.8126 Ls

Hence, 17 MGD = 17 x 43.8126 Ls = 744.8142 Ls
