STEP 1: Convert Input(s) to Base Unit

Maximum Yield Coefficient: 0.5 --> No Conversion Required
Sewage Discharge: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required
Influent BOD: 11.2 Milligram per Liter --> 0.0112 Kilogram per Cubic Meter (Check conversion here)
Effluent BOD: 0.4 Milligram per Liter --> 0.0004 Kilogram per Cubic Meter (Check conversion here)
Mass of Wasted Activated Sludge: 53626 Milligram --> 0.053626 Kilogram (Check conversion here)
Mixed Liquor Suspended Solids: 1200 Milligram per Liter --> 1.2 Kilogram per Cubic Meter (Check conversion here)
Volume of Tank: 9 Cubic Meter --> 9 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K^e = ((Y*Q_s*(Q_i-Q_o))-M_ws)/(X^'*V) --> ((0.5*10*(0.0112-0.0004))-0.053626)/(1.2*9)

Evaluating ... ...

K^e = 3.46296296296302E-05

STEP 3: Convert Result to Output's Unit

3.46296296296302E-05 1 Per Second -->2.99200000000005 1 Per Day (Check conversion here)

FINAL ANSWER

2.99200000000005 ≈ 2.992 1 Per Day <-- Endogenous Respiration Rate Constant
