Endogenous Decay Coefficient given Observed Cell Yield Solution

STEP 0: Pre-Calculation Summary

Formula Used

Endogenous Decay Coefficient = (Observed Cell Yield-Maximum Yield Coefficient)/Mean Cell Residence Time
k_d = (Y_obs-Y)/θ_c
This formula uses 4 Variables

Variables Used

Endogenous Decay Coefficient - (Measured in 1 Per Second) - Endogenous Decay Coefficient refers to the rate at which microorganisms in the biomass consume their own cell mass in the absence of an external food source.
Observed Cell Yield - Observed Cell Yield refers to the observed mg of cells produced per mg organic matter removed.
Maximum Yield Coefficient - Maximum Yield Coefficient refers to the maximum mg of cells produced per mg organic matter removed.
Mean Cell Residence Time - (Measured in Second) - Mean Cell Residence Time is the average time that the sludge remains in the reactor.

STEP 1: Convert Input(s) to Base Unit

Observed Cell Yield: 0.8 --> No Conversion Required
Maximum Yield Coefficient: 0.5 --> No Conversion Required
Mean Cell Residence Time: 7 Day --> 604800 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

k_d = (Y_obs-Y)/θ_c --> (0.8-0.5)/604800

Evaluating ... ...

k_d = 4.96031746031746E-07

STEP 3: Convert Result to Output's Unit

4.96031746031746E-07 1 Per Second -->0.0428571428571429 1 Per Day (Check conversion here)

FINAL ANSWER

0.0428571428571429 ≈ 0.042857 1 Per Day <-- Endogenous Decay Coefficient
