A treatment plant being designed for cynusoidal city requires an equalization basin to even outflow and BOD variations.The average daily flow is 0.400m^3/s.The following flows and BOD5 have been found to be typical of the average variation over a day.What volume equalization basin is required to provide for a uniform outflow equal to the average daily flow?Assume the flows are hourly averages and that an addition of 25% to the estimated volume will be provided to account for contingencies.
