Spray Volume Calculator
Calculate spray volume and coverage from nozzle spacing, flow rate, walking speed, and application rate for agriculture or cleaning work.
This works right here on your device — nothing gets sent out.
Application rate calculator
Estimate spray volume from flow, speed, and swath width.
Estimate only. Follow product label and local requirements; verify nozzle output by calibration.
How it works
- Enter the combined flow rate of the nozzles in litres per minute.
- Add travel speed and effective spray width.
- Review application rate, estimated volume for your area, and tank loads.
FAQ
How is the application rate calculated?
The calculator uses 600 × total nozzle flow in L/min ÷ speed in km/h ÷ swath width in metres to estimate L/ha.
Should I use total flow or one nozzle’s flow?
Use the combined output of all nozzles operating at once. If you only know each nozzle’s flow, sum those values first.
Can I use this estimate as a calibration?
No. It is a planning estimate. Measure actual nozzle output and follow product labels and local application requirements.
