Variables Used

Correction Factor - Correction Factor is that which is multiplied with the result of an equation to correct for a known amount of systematic error.
Oxygen Transferred - (Measured in Kilogram per Second per Watt) - Oxygen Transferred is the amount of oxygen that is moved from the air into the water.
Oxygen Transfer Capacity - (Measured in Kilogram per Second per Watt) - Oxygen Transfer Capacity is the ability of a system, typically in a wastewater treatment context, to transfer oxygen from the air into the water.
Difference between Saturation DO and Operation DO - (Measured in Kilogram per Cubic Meter) - Difference between Saturation DO and Operation DO is the value obtained after subtracting operation DO from saturation DO.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.

STEP 1: Convert Input(s) to Base Unit

Oxygen Transferred: 3 Kilogram per Hour per Kilowatt --> 8.33333333333333E-07 Kilogram per Second per Watt (Check conversion here)
Oxygen Transfer Capacity: 2.03 Kilogram per Hour per Kilowatt --> 5.63888888888889E-07 Kilogram per Second per Watt (Check conversion here)
Difference between Saturation DO and Operation DO: 6600 Milligram per Liter --> 6.6 Kilogram per Cubic Meter (Check conversion here)
Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_f = N/((N^s*D*(1.024)^(T-20))/(9.17)) --> 8.33333333333333E-07/((5.63888888888889E-07*6.6*(1.024)^(85-20))/(9.17))

Evaluating ... ...

C_f = 0.439494490718218

STEP 3: Convert Result to Output's Unit

0.439494490718218 --> No Conversion Required

FINAL ANSWER

0.439494490718218 ≈ 0.439494 <-- Correction Factor

< Operation D.O Level Calculators

Operation Dissolved Oxygen Level

Go Operation Dissolved Oxygen = Dissolved Oxygen Saturation-((Oxygen Transferred*9.17)/(Oxygen Transfer Capacity*Correction Factor*(1.024)^(Temperature-20)))

Operation D.O Level when Correction Factor is 0.85

Go Operation Dissolved Oxygen = D.O Saturation when Correction Factor is 0.85-((Oxygen Transferred*9.17)/(Oxygen Transfer Capacity*0.85*(1.024)^(Temperature-20)))

Operation D.O Level when Correction Factor is 0.8

Go Operation Dissolved Oxygen = D.O Saturation when Correction Factor is 0.8-((Oxygen Transferred*9.17)/(Oxygen Transfer Capacity*0.8*(1.024)^(Temperature-20)))

Correction Factor

Go Correction Factor = Oxygen Transferred/((Oxygen Transfer Capacity*Difference between Saturation DO and Operation DO*(1.024)^(Temperature-20))/(9.17))

< Important Formulas of Oxygen Requirement of the Aeration Tank Calculators

BOD5 given Oxygen Required in Aeration Tank

Go BOD5 given Oxygen Required in Aeration Tank = Ultimate BOD*(Sewage Discharge*(Influent BOD-Effluent BOD))/(Theoretical Oxygen Requirement+(1.42*Volume of Wasted Sludge per day*MLSS in Returned or Wasted Sludge))

BOD5 given Ratio of BOD to Ultimate BOD

Go BOD5 given Ratio of BOD to Ultimate BOD = Ratio of BOD to Ultimate BOD*Ultimate BOD

Ratio of BOD to Ultimate BOD

Go Ratio of BOD to Ultimate BOD = BOD of 5 days at 20° C/Ultimate BOD

BOD5 when Ratio of BOD to Ultimate BOD is 0.68

Go 5 Days BOD = Ultimate BOD*0.68
