A BOD analysis was performed on a municipal wastewater. The 300 mL test bottle was filled with 2.0% wastewater mixed with dillution water, The initial dissolved oxygen (DO) was 8.3 mg/L. The sample is then put in a incubator and set at 20°C. Since the 5th day falls on public holiday, the final DO does not get measured until the 7th day. The final DO is measured at 4.5 mg/L. Assuming k30 (base e) is 0.2/day, determine the BOD3 @ 20°C BOD5 @ 30°C
