Reoxygenation Coefficient given Critical Oxygen Deficit Solution

STEP 0: Pre-Calculation Summary

Formula Used

Reoxygenation coefficient = Deoxygenation Constant*Oxygen Equivalent*(10^(-Deoxygenation Constant*Critical time))/Critical oxygen deficit
K_R = K_D*L_t*(10^(-K_D*t_c))/D_c
This formula uses 5 Variables

Variables Used

Reoxygenation coefficient - (Measured in 1 Per Second) - Reoxygenation coefficient implies the higher the flow velocity, the higher the re-oxygenation coefficient.
Deoxygenation Constant - (Measured in 1 Per Second) - Deoxygenation Constant is the value obtained after decomposing of oxygen in sewage.
Oxygen Equivalent - (Measured in Kilogram per Cubic Meter) - Oxygen Equivalent is the oxidisable organic matter present in sewage.
Critical time - (Measured in Second) - Critical time is the time after which the minimum dissolved oxygen occurs can be found by differentiating the equation.
Critical oxygen deficit - Critical oxygen deficit is the condition where the deoxygenation rate exceeds the reoxygenation rate.

STEP 1: Convert Input(s) to Base Unit

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)
Critical time: 0.5 Day --> 43200 Second (Check conversion here)
Critical oxygen deficit: 6 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_R = K_D*L_t*(10^(-K_D*t_c))/D_c --> 2.66203703703704E-06*0.00021*(10^(-2.66203703703704E-06*43200))/6

Evaluating ... ...

K_R = 7.14960646916973E-11

STEP 3: Convert Result to Output's Unit

7.14960646916973E-11 1 Per Second -->6.17725998936265E-06 1 Per Day (Check conversion here)

FINAL ANSWER

6.17725998936265E-06 ≈ 6.2E-6 1 Per Day <-- Reoxygenation coefficient
