A treatment plant being designed for Cynusoidal City requires an equalization basin to even out flow and BOD variations. The average daily flow is 0.400 m^3/s. The following flows and BOD_5 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

The size of equalization basin is 6105.6 m³

Explanation:

The average flow is:

flow = ∑flow/n = 9.788/24 = 0.408 m³/s

Where n is the number or observations.

The inflow volume is:

where t is the time interval

in the same way it is calculated the inflow volume for each observation

The outflow volume is:

The volume of flow is:

in the same way it is calculated the volume of flow for each observation. According to the file attach, the highest volume is 6105.6 m³
