BOD of Effluent Getting Out of Filter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effluent BOD = Influent BOD*exp(-1*Reaction Rate Constant*Depth*(Hydraulic Loading)^(-1*Empirical Constant))
Q_o = Q_i*exp(-1*K_d*D*(H)^(-1*A₀))
This formula uses 1 Functions, 6 Variables

Functions Used

exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)

Variables Used

Effluent BOD - (Measured in Kilogram per Cubic Meter) - Effluent BOD is the amount of BOD present in the outing sewage.
Influent BOD - (Measured in Kilogram per Cubic Meter) - Influent BOD is the total amount of BOD which is present in the incoming sewage.
Reaction Rate Constant - (Measured in 1 Per Second) - Reaction Rate Constant quantifies the rate and direction of a chemical reaction.
Depth - (Measured in Meter) - Depth is the distance from the top or surface to the bottom of something.
Hydraulic Loading - (Measured in Meter per Second) - Hydraulic loading is the volume of water applied to a treatment system, such as a wastewater treatment plant or a soil absorption system, per unit area per unit time.
Empirical Constant - The Empirical constant is a self determined constant whose value is accessible from table of such constants. This constant is used to calculate the intrinsic carrier concentration.

STEP 1: Convert Input(s) to Base Unit

Influent BOD: 12.6 Milligram per Liter --> 0.0126 Kilogram per Cubic Meter (Check conversion here)
Reaction Rate Constant: 0.05 1 Per Day --> 5.78703703703704E-07 1 Per Second (Check conversion here)
Depth: 3 Meter --> 3 Meter No Conversion Required
Hydraulic Loading: 0.865 Meter per Second --> 0.865 Meter per Second No Conversion Required
Empirical Constant: 100 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_o = Q_i*exp(-1*K_d*D*(H)^(-1*A₀)) --> 0.0126*exp(-1*5.78703703703704E-07*3*(0.865)^(-1*100))

Evaluating ... ...

Q_o = 0.000399525972303241

STEP 3: Convert Result to Output's Unit

0.000399525972303241 Kilogram per Cubic Meter -->0.399525972303241 Milligram per Liter (Check conversion here)

FINAL ANSWER

0.399525972303241 ≈ 0.399526 Milligram per Liter <-- Effluent BOD

(Calculation completed in 00.021 seconds)
