Two industries Fuzzy Chemicals and Super Agra want to discharge their wastewater into the Delaware River (upstream flow of Q3) through a single channel. Fuzzy Chemicals has a flow of 2 MGD (Q.) and a phenol concentration of C2 while Super Agra has a flow of 20 MGD (Q1) with a phenol concentration of C1. The phenol concentration upstream of the factories is negligible. What is the correct expression to determine the phenol concentration C just downstream of the factories? OC - (Q:C: +QzC2+Q3(C+C)/(Q+Q+Q2) OC - IC: +C) (Qz+Q2)/(Qz+Q+Q3) OC. (Q.C1 Q2C)/(Q) OC - (QC1 + Q2C)/(Qz+Q,+Q3) The numerical values for the flows and concentrations identified in the previous question are the following: Q3 - 8 MGD Q2 - 2 MGD, C2 -0.08 mg/L Q1 - 20 MGD, C1 -0.05 mg/L What is the phenol concentration downstream of the factories? (in mg/L)
