Oxygen Equivalent - (Measured in Kilogram per Cubic Meter) - The Oxygen Equivalent is referred as the oxidizable organic matter present in sewage.

STEP 1: Convert Input(s) to Base Unit

Critical Oxygen Deficit: 0.0003 --> No Conversion Required
Reoxygenation Coefficient: 0.22 1 Per Day --> 2.5462962962963E-06 1 Per Second (Check conversion here)
Deoxygenation Constant: 0.23 1 Per Day --> 2.66203703703704E-06 1 Per Second (Check conversion here)
Oxygen Equivalent: 0.21 Milligram per Liter --> 0.00021 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_c = log10((D_c*K_R)/(K_D*L_t))/K_D --> log10((0.0003*2.5462962962963E-06)/(2.66203703703704E-06*0.00021))/2.66203703703704E-06

Evaluating ... ...

t_c = 50937.23449516

STEP 3: Convert Result to Output's Unit

50937.23449516 Second -->0.589551325175463 Day (Check conversion here)

FINAL ANSWER

0.589551325175463 ≈ 0.589551 Day <-- Critical Time
