A BOD analysis was begun on Monday. Fifteen ml of waste with a DO of zero was mixed with $270$ mL of dilution water with a DO of $9$ mg$/$L$.$ The sample was then put in the incubator. Since the $5$th day fell on a long weekend $($Friday$)$ and lab personnel do not work on Saturday, the final DO did not get measured until Monday, the eighth day. The final DO was measured at $2\mathrm{.}8$ mg$/$L$.$ However, it was discovered that the incubator was mistakenly set at $32\backslash$deg C$.$ Assume a kl of $0\mathrm{.}15$ day$1$ at $20\backslash$deg C and $0-1\mathrm{.}05.$ Determine the $5-$day $20\backslash$deg C BOD of the sample. Also, what is the ultimate CBOD at $32\backslash$deg C and $20\backslash$deg C; Will it vary?
