An in$-$line equalization basin is to be designed for an industrial wastewater pretreatment plant. From plant records, a $24-$hour compilation has been made that gives the following hourly flowrates and total organic carbon $($TOC$)$ concentration data:

$\backslash$table$[[$Time period,$\backslash$table$[[$Average flowrate during$],[$time period$],[($Liters per minute$)]],\backslash$table$[[$Average TOC$],[$concentration during$],[$time period$],[(m\frac{g}{L})$
