Number of Coliform Organisms at Any Initial Time Solution

STEP 0: Pre-Calculation Summary
Formula Used
Number of Coliform = (Number of coliform/(1+0.23*Chlorine residual*Residence time)^(-3))
N0 = (Nt/(1+0.23*Ct*t)^(-3))
This formula uses 4 Variables
Variables Used
Number of Coliform - Number of coliform present at initial time t0.
Number of coliform - Number of coliform present at time t.
Chlorine residual - (Measured in Kilogram per Cubic Meter) - Chlorine residual means total chlorine residual at time t.
Residence time - (Measured in Second) - Residence time is defined as the amount of water in a reservoir divided by the rate of addition of water .
STEP 1: Convert Input(s) to Base Unit
Number of coliform: 3 --> No Conversion Required
Chlorine residual: 5 Milligram per Liter --> 0.005 Kilogram per Cubic Meter (Check conversion here)
Residence time: 20 Minute --> 1200 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
N0 = (Nt/(1+0.23*Ct*t)^(-3)) --> (3/(1+0.23*0.005*1200)^(-3))
Evaluating ... ...
N0 = 40.443816
STEP 3: Convert Result to Output's Unit
40.443816 --> No Conversion Required
FINAL ANSWER
40.443816 40.44382 <-- Number of Coliform
(Calculation completed in 00.004 seconds)

Residence Time given Number of Coliform Organisms at Any Particular Time
Go Residence time = ((Number of Coliform/Number of coliform)^(1/3)-1)/(0.23*Chlorine residual)
Total Chlorine Residual at Any Particular Time
Go Chlorine residual = ((Number of Coliform/Number of coliform)^(1/3)-1)/(0.23*Residence time)
Number of Coliform Organisms at Any Initial Time
Go Number of Coliform = (Number of coliform/(1+0.23*Chlorine residual*Residence time)^(-3))
Number of Coliform Organisms at Any Particular Time
Go Number of coliform = Number of Coliform*(1+0.23*Chlorine residual*Residence time)^(-3)
Peaking Factor given Capacity of Chlorinator at Peak Flow
Go Peaking factor = (Chlorine required/(Average flow*8.34*Dosage))
Average Flow given Capacity of Chlorinator at Peak Flow
Go Average flow = (Chlorine required/(Dosage*Peaking factor*8.34))
Dosage Used given Capacity of Chlorinator at Peak Flow
Go Dosage = (Chlorine required/(Peaking factor*Average flow*8.34))
Capacity of Chlorinator at Peak Flow
Go Chlorine required = Dosage*Average flow*8.34*Peaking factor
Average Flow given Average Daily Consumption of Chlorine
Go Average flow = (Chlorine required/(Dosage*8.34))
Dosage Used given Average Daily Consumption of Chlorine
Go Dosage = (Chlorine required/(8.34*Average flow))
Average Daily Consumption of Chlorine
Go Chlorine required = Dosage*Average flow*8.34
