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 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 is the oxidisable organic matter present in sewage.
Deoxygenation Constant - (Measured in 1 Per Second) - Deoxygenation Constant is 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: 10 Day --> 864000 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*864000)

Evaluating ... ...

L = 0.0419005086143467

STEP 3: Convert Result to Output's Unit

0.0419005086143467 Kilogram per Cubic Meter -->41.9005086143467 Milligram per Liter (Check conversion here)

FINAL ANSWER

41.9005086143467 ≈ 41.90051 Milligram per Liter <-- Organic Matter at Start

(Calculation completed in 00.004 seconds)
