BOD in given Percent Stabilization Solution

STEP 0: Pre-Calculation Summary
Formula Used
BOD in = (BOD out*100+142*Volatile Solids produced)/(100-Percent stabilization)
BODin = (BODout*100+142*Px)/(100-%S)
This formula uses 4 Variables
Variables Used
BOD in - (Measured in Kilogram per Second) - BOD in means the amount of dissolved oxygen enter anaerobic digester.
BOD out - (Measured in Kilogram per Second) - BOD out means the amount of dissolved oxygen exits anaerobic digester.
Volatile Solids produced - (Measured in Kilogram per Second) - Volatile solids produced is defined in terms of mass flow rate.
Percent stabilization - Percent stabilization is defined as percentage of bod removal.
STEP 1: Convert Input(s) to Base Unit
BOD out: 5 Kilogram per Day --> 5.78703703703704E-05 Kilogram per Second (Check conversion here)
Volatile Solids produced: 100 Kilogram per Day --> 0.00115740740740741 Kilogram per Second (Check conversion here)
Percent stabilization: 0.8 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
BODin = (BODout*100+142*Px)/(100-%S) --> (5.78703703703704E-05*100+142*0.00115740740740741)/(100-0.8)
Evaluating ... ...
BODin = 0.00171510976702509
STEP 3: Convert Result to Output's Unit
0.00171510976702509 Kilogram per Second -->148.185483870968 Kilogram per Day (Check conversion here)
FINAL ANSWER
148.185483870968 148.1855 Kilogram per Day <-- BOD in
