Deoxygenation Constant given Total Amount of Organic Matter Oxidised Solution

STEP 0: Pre-Calculation Summary

Formula Used

Deoxygenation Constant = -(1/Time in days)*log10(1-(Organic Matter Oxidised/Organic Matter at Start))
K_D = -(1/t)*log10(1-(Y_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.
Organic Matter Oxidised - (Measured in Milligram per Liter) - Organic Matter Oxidised is the total amount of organic matter which is oxidised during the BOD reaction.
Organic Matter at Start - (Measured in Milligram per Liter) - 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)
Organic Matter Oxidised: 0.4 Milligram per Liter --> 0.4 Milligram per Liter No Conversion Required
Organic Matter at Start: 40 Milligram per Liter --> 40 Milligram per Liter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_D = -(1/t)*log10(1-(Y_t/L)) --> -(1/864000)*log10(1-(0.4/40))

Evaluating ... ...

K_D = 5.0518581046876E-09

STEP 3: Convert Result to Output's Unit

5.0518581046876E-09 1 Per Second -->0.000436480540245009 1 Per Day (Check conversion here)

FINAL ANSWER

0.000436480540245009 ≈ 0.000436 1 Per Day <-- Deoxygenation Constant
