Enter the weight of H2O lost by transpiration (kg) and the weight of dry material produced into the Transpiration Rate Calculator. The calculator will evaluate the Transpiration Rate.

## Transpiration Rate Formula

The following two example problems outline the steps and information needed to calculate the Transpiration Rate.

TR = H2O / DM

Variables:

- TR is the Transpiration Rate (kg H2O:dry material)
- H2O is the weight of H2O lost by transpiration (kg)
- DM is the weight of dry material produced

To calculate the transpiration rate, divide the weight of H2O lost by transpiration by the weight of the dry material produced.

## How to Calculate Transpiration Rate?

The following steps outline how to calculate the Transpiration Rate.

- First, determine the weight of H2O lost by transpiration (kg).
- Next, determine the weight of dry material produced.
- Next, gather the formula from above = TR = H2O / DM.
- Finally, calculate the Transpiration Rate.
- 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.

weight of H2O lost by transpiration (kg) = 34

weight of dry material produced = 57

TR = H2O / DM** **= ?
