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 refers to the duration that wastewater remains in contact with a disinfectant agent within a treatment process.
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 refers to the concentration of chlorine remaining in water after it has been treated with chlorine-based disinfectants.

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 00.020 seconds)
