Enter the total volume (m^3) and the flow rate (m^3/s) into the Calculator. The calculator will evaluate the Duration Of Flow.

## Duration Of Flow Formula

DOF = V / FR

Variables:

- DOF is the Duration Of Flow (seconds)
- V is the total volume (m^3)
- FR is the flow rate (m^3/s)

To calculate Duration Of Flow, divide the total volume by the total flow rate.

## How to Calculate Duration Of Flow?

The following steps outline how to calculate the Duration Of Flow.

- First, determine the total volume (m^3).
- Next, determine the flow rate (m^3/s).
- Next, gather the formula from above = DOF = V / FR.
- Finally, calculate the Duration Of Flow.
- 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.

total volume (m^3) = 400

flow rate (m^3/s) = 500
