Organic Matter Present at Start of BOD Solution

STEP 0: Pre-Calculation Summary

Formula Used

Organic Matter at Start = Oxygen Equivalent/10^(-Deoxygenation Constant*Time in Days)
L = L_t/10^(-K_D*t)
This formula uses 4 Variables

Variables Used

Organic Matter at Start - (Measured in Kilogram per Cubic Meter) - Organic Matter at Start is referred as the total organic matter present in the sewage at the start of the BOD reaction.
Oxygen Equivalent - (Measured in Kilogram per Cubic Meter) - Oxygen Equivalent refers to the oxidizable organic matter present in sewage.
Deoxygenation Constant - (Measured in 1 Per Second) - Deoxygenation Constant refers to the value obtained after decomposing of oxygen in sewage.
Time in Days - (Measured in Second) - Time in Days is the time calculated in days.

STEP 1: Convert Input(s) to Base Unit

Oxygen Equivalent: 0.21 Milligram per Liter --> 0.00021 Kilogram per Cubic Meter (Check conversion here)
Deoxygenation Constant: 0.23 1 Per Day --> 2.66203703703704E-06 1 Per Second (Check conversion here)
Time in Days: 9 Day --> 777600 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L = L_t/10^(-K_D*t) --> 0.00021/10^(-2.66203703703704E-06*777600)

Evaluating ... ...

L = 0.0246728486537303

STEP 3: Convert Result to Output's Unit

0.0246728486537303 Kilogram per Cubic Meter -->24.6728486537303 Milligram per Liter (Check conversion here)

FINAL ANSWER

24.6728486537303 ≈ 24.67285 Milligram per Liter <-- Organic Matter at Start

(Calculation completed in 00.004 seconds)
