Final Efficiency after Two Stage Filtration Solution

STEP 0: Pre-Calculation Summary
Formula Used
Efficiency of Second Filter Stage = (100/(1+(0.0044/(1-Efficiency of First Filter Stage))*sqrt(BOD in Effluent/(Volume*Recirculation Factor))))
E2 = (100/(1+(0.0044/(1-E1))*sqrt(Y'/(VT*F))))
This formula uses 1 Functions, 5 Variables
Functions Used
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Efficiency of Second Filter Stage - Efficiency of second filter stage is the total efficiency obtained from the second trickling filter.
Efficiency of First Filter Stage - Efficiency of first filter stage calculates the efficiency of the filter at the first stage.
BOD in Effluent - (Measured in Kilogram per Second) - BOD in Effluent means total BOD in effluent from 1st stage.
Volume - (Measured in Cubic Meter) - Volume is the three-dimensional space occupied by a substance or object, such as water, soil, air, or any environmental medium.
Recirculation Factor - Recirculation factor r represents the average number of passes of the influent organic matter through the trickling filter.
STEP 1: Convert Input(s) to Base Unit
Efficiency of First Filter Stage: 99.5 --> No Conversion Required
BOD in Effluent: 3 Kilogram per Day --> 3.47222222222222E-05 Kilogram per Second (Check conversion ​here)
Volume: 0.63 Cubic Meter --> 0.63 Cubic Meter No Conversion Required
Recirculation Factor: 1.116 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
E2 = (100/(1+(0.0044/(1-E1))*sqrt(Y'/(VT*F)))) --> (100/(1+(0.0044/(1-99.5))*sqrt(3.47222222222222E-05/(0.63*1.116))))
Evaluating ... ...
E2 = 100.000031391926
STEP 3: Convert Result to Output's Unit
100.000031391926 --> No Conversion Required
FINAL ANSWER
100.000031391926 100 <-- Efficiency of Second Filter Stage
