Food to Microorganism Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Food to Microorganism Ratio = Daily BOD/Total Microbial Mass
FM = BOD/M_t
This formula uses 3 Variables

Variables Used

Food to Microorganism Ratio - Food to Microorganism Ratio is actually a measurement of the amount of incoming food divided by the Lbs of Microorganisms in your system.
Daily BOD - (Measured in Kilogram) - Daily BOD load measures the amount of oxygen that microorganisms will consume while decomposing organic matter in a water sample over a 24-hour period.
Total Microbial Mass - (Measured in Kilogram) - Total Microbial Mass is the cumulative mass of microorganisms present in a given sample or system. This includes bacteria, fungi, protozoa, and other microbes.

STEP 1: Convert Input(s) to Base Unit

Daily BOD: 3 Milligram --> 3E-06 Kilogram (Check conversion here)
Total Microbial Mass: 3 Gram --> 0.003 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

FM = BOD/M_t --> 3E-06/0.003

Evaluating ... ...

FM = 0.001

STEP 3: Convert Result to Output's Unit

0.001 --> No Conversion Required

FINAL ANSWER

0.001 <-- Food to Microorganism Ratio

(Calculation completed in 00.004 seconds)
