STEP 1: Convert Input(s) to Base Unit

Sewage Discharge: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required
Influent BOD: 13.2 Milligram per Liter --> 0.0132 Kilogram per Cubic Meter (Check conversion here)
Effluent BOD: 0.4 Milligram per Liter --> 0.0004 Kilogram per Cubic Meter (Check conversion here)
5 Days BOD: 1.36 Milligram per Liter --> 0.00136 Kilogram per Cubic Meter (Check conversion here)
Ultimate BOD: 2 Milligram per Liter --> 0.002 Kilogram per Cubic Meter (Check conversion here)
Theoretical Oxygen Requirement: 2.5 Milligram per Day --> 2.89351851851852E-11 Kilogram per Second (Check conversion here)
Oxygen Demand of Biomass: 2.02 --> No Conversion Required
MLSS: 1200 Milligram per Liter --> 1.2 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_w' = (((Q_s*(Q_i-Q))/(BOD5/BOD^u))-O₂)/(D^O2*X) --> (((10*(0.0132-0.0004))/(0.00136/0.002))-2.89351851851852E-11)/(2.02*1.2)

Evaluating ... ...

V_w' = 0.0776548242940231

STEP 3: Convert Result to Output's Unit

0.0776548242940231 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.0776548242940231 ≈ 0.077655 Cubic Meter per Second <-- Volume of Wasted Sludge
