Number of Coliform Organisms at Any Particular Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Coliform at Initial Time = Number of Coliform*(1+0.23*Chlorine Residual*Residence Time)^(-3)
N_t = N₀*(1+0.23*C_t*t)^(-3)
This formula uses 4 Variables

Variables Used

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.
Number of Coliform - Number of Coliform present at initial time t0.
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.
Residence Time - (Measured in Second) - Residence Time refers to the duration that wastewater remains in contact with a disinfectant agent within a treatment process.

STEP 1: Convert Input(s) to Base Unit

Number of Coliform: 4 --> No Conversion Required
Chlorine Residual: 0.364646 Milligram per Liter --> 0.000364646 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

N_t = N₀*(1+0.23*C_t*t)^(-3) --> 4*(1+0.23*0.000364646*1200)^(-3)

Evaluating ... ...

N_t = 3.0000009836838

STEP 3: Convert Result to Output's Unit

3.0000009836838 --> No Conversion Required

FINAL ANSWER

3.0000009836838 ≈ 3.000001 <-- Number of Coliform at Initial Time

(Calculation completed in 00.004 seconds)
