Enter the volume of the empty bed (gallons) and the flow rate (GPM) into the Calculator. The calculator will evaluate the Empty Bet Contact Time.

## Empty Bet Contact Time Formula

EBCT = V / FR

Variables:

- EBCT is the Empty Bet Contact Time (minutes)
- V is the volume of empty bed (gallons)
- FR is the flow rate (GPM)

To calculate Empty Bet Contact Time, divide the empty bed volume by the flow rate.

## How to Calculate Empty Bet Contact Time?

The following steps outline how to calculate the Empty Bet Contact Time.

- First, determine the volume of the empty bed (gallons).
- Next, determine the flow rate (GPM).
- Next, gather the formula from above = EBCT = V / FR.
- Finally, calculate the Empty Bet Contact Time.
- 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.

volume of empty bed (gallons) = 500

flow rate (GPM) = 700
