The Spray Rate Calculator can be used to calculate the hectares covered per minute of flight. When setting up a new spray boom you need to understand how much can be delivered from your setup. By adjusting various inputs you can try different swath, and speed measurement's to ensure your application rate remains correct for the spray you are delivering.

THE SECRET FORMULA

First its not a secret. You will find this formula in plenty of books.

(Swath width (meters) X Speed (Knots) Aircraft Calibrated) / 324 (mathematical constant) = Hectares covered / minute flight.

Add the amount from each nozzle, the amount of nozzles you have and you can get the answer.

CALIBRATION

Correct spray gear calibration is essential for ensuring correct application rates. This FREE app is designed to make it easy to move around the constants to allow you to try out various setups and see what works for you!
