BOD5 when Ratio of BOD to Ultimate BOD is 0.68 Solution

STEP 0: Pre-Calculation Summary
Formula Used
5 days BOD = Ultimate BOD*0.68
BOD5 = BODu*0.68
This formula uses 2 Variables
Variables Used
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.
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.
STEP 1: Convert Input(s) to Base Unit
Ultimate BOD: 2 Milligram per Liter --> 0.002 Kilogram per Cubic Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
BOD5 = BODu*0.68 --> 0.002*0.68
Evaluating ... ...
BOD5 = 0.00136
STEP 3: Convert Result to Output's Unit
0.00136 Kilogram per Cubic Meter -->1.36 Milligram per Liter (Check conversion here)
FINAL ANSWER
1.36 Milligram per Liter <-- 5 days BOD
(Calculation completed in 00.004 seconds)
