Residence Time given Number of Coliform Organisms at Any Particular Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Residence time = ((Number of Coliform/Number of coliform at initial time)^(1/3)-1)/(0.23*Chlorine residual)
t = ((N₀/N_t)^(1/3)-1)/(0.23*C_t)
This formula uses 4 Variables

Variables Used

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 .
Number of Coliform - Number of coliform present at initial time t0.
Number of coliform at initial time - Number of coliform at initial time number of coliform bacteria present in the initial sample would then be estimated by counting the number of colonies that grow on the culture medium.
Chlorine residual - (Measured in Kilogram per Cubic Meter) - Chlorine residual means total chlorine residual at time t.

STEP 1: Convert Input(s) to Base Unit

Number of Coliform: 4 --> No Conversion Required
Number of coliform at initial time: 3 --> No Conversion Required
Chlorine residual: 0.364646 Milligram per Liter --> 0.000364646 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t = ((N₀/N_t)^(1/3)-1)/(0.23*C_t) --> ((4/3)^(1/3)-1)/(0.23*0.000364646)

Evaluating ... ...

t = 1200.00143436563

STEP 3: Convert Result to Output's Unit

1200.00143436563 Second -->20.0000239060939 Minute (Check conversion here)

FINAL ANSWER

20.0000239060939 ≈ 20.00002 Minute <-- Residence time

(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 at initial time)^(1/3)-1)/(0.23*Chlorine residual)

Total Chlorine Residual at Any Particular Time

Go Chlorine residual = ((Number of Coliform/Number of coliform at initial time)^(1/3)-1)/(0.23*Residence time)

Number of Coliform Organisms at Any Initial Time

Go Number of Coliform = (Number of coliform at initial time/(1+0.23*Chlorine residual*Residence time)^(-3))

Number of Coliform Organisms at Any Particular Time

Go Number of coliform at initial time = 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

Residence Time given Number of Coliform Organisms at Any Particular Time Formula

Residence time = ((Number of Coliform/Number of coliform at initial time)^(1/3)-1)/(0.23*Chlorine residual)
t = ((N₀/N_t)^(1/3)-1)/(0.23*C_t)

What is residence time ?

Residence time is defined as the amount of water in a reservoir divided by either the rate of addition of water to the reservoir or the rate of loss from it.
