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)
K_D = -(1/t)*log10(L_t/L)
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 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.
Oxygen Equivalent - (Measured in Kilogram per Cubic Meter) - Oxygen Equivalent is the oxidisable organic matter present in sewage.
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.

STEP 1: Convert Input(s) to Base Unit

Time in days: 10 Day --> 864000 Second (Check conversion here)
Oxygen Equivalent: 0.21 Milligram per Liter --> 0.00021 Kilogram per Cubic Meter (Check conversion here)
Organic Matter at Start: 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) --> -(1/864000)*log10(0.00021/0.04)

Evaluating ... ...

K_D = 2.63870450994681E-06

STEP 3: Convert Result to Output's Unit

2.63870450994681E-06 1 Per Second -->0.227984069659404 1 Per Day (Check conversion here)

FINAL ANSWER

0.227984069659404 ≈ 0.227984 1 Per Day <-- Deoxygenation Constant

(Calculation completed in 00.004 seconds)
