`F_r = V / D `

Enter a value for all fields

The **Flow Rate **calculator computes the flow rate based on a the total volume of flow and the duration it took to accumulate the volume.

**INSTRUCTIONS**: Choose units and enter the following:

- (
**V**) Total Volume - (
**D**) Duration of time

**Flow Rate (FR): **The calculator returns the average flow rate in gallons per minute. However, this can be automatically converted to compatible units via the pull-down menu.

The formula for flow rate is:

FR = V / D

where:

- FR = Flow rate
- V = Total Volume
- D = Duration required to accumulate volume
