Deoxygenation Constant given Organic Matter Present at Start of BOD Solution

STEP 0: Pre-Calculation Summary

Formula Used

Deoxygenation Constant = -(1/Time in Days)*log10(Oxygen Equivalent/Organic Matter at Start s)
K_D = -(1/t)*log10(L_t/L_s)
This formula uses 1 Functions, 4 Variables

Functions Used

log10 - The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function., log10(Number)

Variables Used

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.
Oxygen Equivalent - (Measured in Kilogram per Cubic Meter) - Oxygen Equivalent refers to the oxidizable organic matter present in sewage.
Organic Matter at Start s - (Measured in Kilogram per Cubic Meter) - Organic Matter at Start s refers to the total organic matter present in the sewage at the start of the BOD reaction.

STEP 1: Convert Input(s) to Base Unit

Time in Days: 9 Day --> 777600 Second (Check conversion here)
Oxygen Equivalent: 0.21 Milligram per Liter --> 0.00021 Kilogram per Cubic Meter (Check conversion here)
Organic Matter at Start s: 40 Milligram per Liter --> 0.04 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_D = -(1/t)*log10(L_t/L_s) --> -(1/777600)*log10(0.00021/0.04)

Evaluating ... ...

K_D = 2.9318938999409E-06

STEP 3: Convert Result to Output's Unit

2.9318938999409E-06 1 Per Second -->0.253315632954894 1 Per Day (Check conversion here)

FINAL ANSWER

0.253315632954894 ≈ 0.253316 1 Per Day <-- Deoxygenation Constant
