Time given Organic Matter Present at Start of BOD Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time in Days = -(1/Deoxygenation Constant)*log10(Oxygen Equivalent/Organic Matter at Start s)
t = -(1/K_D)*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

Time in Days - (Measured in Second) - Time in Days is the time calculated in days.
Deoxygenation Constant - (Measured in 1 Per Second) - Deoxygenation Constant refers to the value obtained after decomposing of oxygen in sewage.
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

Deoxygenation Constant: 0.23 1 Per Day --> 2.66203703703704E-06 1 Per 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

t = -(1/K_D)*log10(L_t/L_s) --> -(1/2.66203703703704E-06)*log10(0.00021/0.04)

Evaluating ... ...

t = 856427.113850979

STEP 3: Convert Result to Output's Unit

856427.113850979 Second -->9.9123508547567 Day (Check conversion here)

FINAL ANSWER

9.9123508547567 ≈ 9.912351 Day <-- Time in Days

(Calculation completed in 00.004 seconds)
