Ultimate BOD given Ratio of BOD to Ultimate BOD Solution

STEP 0: Pre-Calculation Summary

Formula Used

Ultimate BOD = 5 days BOD/Ratio of BOD to Ultimate BOD
BOD^u = BOD5/f
This formula uses 3 Variables

Variables Used

Ultimate BOD - (Measured in Kilogram per Cubic Meter) - Ultimate BOD is the amount of oxygen required to decompose all of the organic material after infinite time.
5 days BOD - (Measured in Kilogram per Cubic Meter) - 5 days BOD is an indicator of how much oxygen is utilized by a natural water sample in five days at 20 degrees C.
Ratio of BOD to Ultimate BOD - Ratio of BOD to Ultimate BOD is the ratio of 5 days bod to ultimate bod.

STEP 1: Convert Input(s) to Base Unit

5 days BOD: 2 Milligram per Liter --> 0.002 Kilogram per Cubic Meter (Check conversion here)
Ratio of BOD to Ultimate BOD: 1.6 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BOD^u = BOD5/f --> 0.002/1.6

Evaluating ... ...

BOD^u = 0.00125

STEP 3: Convert Result to Output's Unit

0.00125 Kilogram per Cubic Meter -->1.25 Milligram per Liter (Check conversion here)

FINAL ANSWER

1.25 Milligram per Liter <-- Ultimate BOD

(Calculation completed in 00.004 seconds)
