Enter the flow rate of the spray (GPM) and the total time (minutes) into the Spray Volume Calculator. The calculator will evaluate and display the Spray Volume. 

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:

  1. First, determine the flow rate of the spray (GPM). 
    1. The flow rate of the spray (GPM) is given as: 10.
  2. Next, determine the total time (minutes). 
    1. The total time (minutes) is provided as: 40.
  3. 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)
