## Spray Volume Formula

The following formula is used to calculate the Spray Volume.

**SPV = FS * T**

- Where SPV is the Spray Volume (gallons)
- FS is the flow rate of the spray (GPM)
- T is the total time (minutes)

## How to Calculate Spray Volume?

The following example problems outline how to calculate Spray Volume.

Example Problem #1:

- First, determine the flow rate of the spray (GPM).
- The flow rate of the spray (GPM) is given as: 10.

- Next, determine the total time (minutes).
- The total time (minutes) is provided as: 40.

- Finally, calculate the Spray Volume using the equation above:

SPV = FS * T

The values given above are inserted into the equation below:

SPV = 10 * 40 = 400 (gallons)

Example Problem #2:** **

The variables needed for this problem are provided below:

flow rate of the spray (GPM) = 30

total time (minutes) = 20

Entering these values and solving gives:

SPV = 30 * 20 = 600 (gallons)
