A student began an experiment of 5 day 20°C BOD on Monday. Since the 5th day fell on Saturday. The final DO reading was taken on Monday. On calculation BOD (i.e. 7 day 20°C) was found to be 150 mg/L. What would be the 5 day, 20°C BOD (in mg/L). Assume value of BOD rate constant (K) at standard temperature of 20°C as 0.23/day (base e).
