CAUTION: Maintain significant figures through all calculations! A tracer study was conducted on a full-scale reactor that has a volume of 780,000 gallons by injecting a slug of chloride into the influent and then measuring the effluent concentration with time. 25 36 43 45 46 Time (minutes after dye was injected) 0.10 0.20 0.30 0.40 0.50 0.75 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 Chloride Concentration (mg/L) 0.0 5.0 5.5 6.0 6.6 7.4 8.6 9.4 10 11 12 13 14 15 5.0 6.0 7.0 8.0 9.0 10 11 12 13 14 15 45 44 21 9.8 8.7 7.3 6.2 5.6 4.7 4.1 3.0 16 17 18 19 20 1.
