Formula Used

Endogenous Coefficient = (1/Mean Cell Residence Time)-(Yield Coefficient*(BOD In-BOD Out)/(Volatile Solids Produced*Mean Cell Residence Time))
k_d = (1/θ_c)-(Y*(BOD_in-BOD_out)/(P_x*θ_c))
This formula uses 6 Variables

Variables Used

Endogenous Coefficient - (Measured in 1 Per Second) - Endogenous Coefficient is referred as modeling the behavior of microorganisms, particularly in wastewater treatment processes.
Mean Cell Residence Time - (Measured in Second) - Mean Cell Residence Time refers to a measure of the extent to which organic matter in sludge has been decomposed or stabilized through treatment processes.
Yield Coefficient - Yield Coefficient is referred as the ratio of biomass (microbial cells) produced to the amount of substrate (organic material) consumed during the digestion process.
BOD In - (Measured in Kilogram per Second) - BOD In in anaerobic digester design lies in its role as an indicator of the organic load present in the feedstock. High BOD levels suggest a greater concentration of organic matter.
BOD Out - (Measured in Kilogram per Second) - BOD Out referred as the amount of dissolved oxygen exits anaerobic digester.
Volatile Solids Produced - (Measured in Kilogram per Second) - Volatile Solids Produced refers to the organic fraction of the total solids present in the sludge.

STEP 1: Convert Input(s) to Base Unit

Mean Cell Residence Time: 6.96 Day --> 601344 Second (Check conversion here)
Yield Coefficient: 0.41 --> No Conversion Required
BOD In: 164 Kilogram per Day --> 0.00189814814814815 Kilogram per Second (Check conversion here)
BOD Out: 4.9 Kilogram per Day --> 5.6712962962963E-05 Kilogram per Second (Check conversion here)
Volatile Solids Produced: 100 Kilogram per Day --> 0.00115740740740741 Kilogram per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

k_d = (1/θ_c)-(Y*(BOD_in-BOD_out)/(P_x*θ_c)) --> (1/601344)-(0.41*(0.00189814814814815-5.6712962962963E-05)/(0.00115740740740741*601344))

Evaluating ... ...

k_d = 5.78188191783739E-07

STEP 3: Convert Result to Output's Unit

5.78188191783739E-07 1 Per Second -->0.0499554597701151 1 Per Day (Check conversion here)

FINAL ANSWER

0.0499554597701151 ≈ 0.049955 1 Per Day <-- Endogenous Coefficient
