Determine the total rinse water rate for a countercurrent rinsing configuration with three tanks, for a process bath with a copper concentration of 35,270 mg/L and a dragout rate of 0.10 mg/L. It is required to keep the copper concentration on the final product to no more than 35 mg/L. Assume the incoming clean rinse water contains 0.005 mg/L zinc, 0.001 mg/L nickel, and no copper. The copper plating bath has an evaporation rate of 0.12 L/min.
