Enter the original water level (gallons) and the final water level (gallons) into the Calculator. The calculator will evaluate the Evaporation Loss.

## Evaporation Loss Formula

EL = OWV - FWV

Variables:

• EL is the Evaporation Loss (gallons)
• OWV is the original water level (gallons)
• FWV is the final water level (gallons)

To calculate Evaporation Loss, subtract the final water level after evaporation from the original water level.

## How to Calculate Evaporation Loss?

The following steps outline how to calculate the Evaporation Loss.

1. First, determine the original water level (gallons).
2. Next, determine the final water level (gallons).
3. Next, gather the formula from above = EL = OWV – FWV.
4. Finally, calculate the Evaporation Loss.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

original water level (gallons) = 4300

final water level (gallons) = 3000
