please solve 8.2 and 8.5

-2. A treatment plant being designed for Metuchen requires an equalization basin to even out flow and BOD variations. The following flows and BOD5 have been found to be typical of the average variation over a day. What size equalization basin, in cubic meters, is required to provide for a uniform outflow equal to the average daily flow? Assume the flows are hourly averages. 8-4. Compute and plot the unequalized and the equalized hourly BOD mass loadings to the Cynusoidal City WWTP (Problem 8-1). Using the plot and computations, determine the following ratios for BOD mass loading: peak to average; minimum to average; peak to minimum. Answers: 8-5. Repeat Problem 8-4 using the data from Problem 8-2
