Spray pattern of nozzle systems

A method of dispersing fluids or fine granular particles from an agricultural vehicle, the method comprising:

• dispensing the fluids or fine granular particles through a first nozzle and a second nozzle;
• sensing at least one of the following:
• vehicle travel speed, vehicle travel direction, wind speed, wind direction, a first height of the first nozzle from a ground surface, and a second height of the second nozzle from the ground surface;
• computing, with a processor, a first spray pattern on the ground surface based on an expected fan angle from a look-up table having fan angles of the first and second nozzles of fluids or fine granular particles dispensed through the first nozzle, and at least one of the following:
• the sensed vehicle travel speed, the sensed vehicle travel direction, the sensed wind speed, the sensed wind direction, and the sensed height of the first nozzle from the ground surface;
• computing, with the processor, a second spray pattern on the ground surface based on an expected angle from the look-up table having fan angles of the first and second nozzles of fluid or fine granular particles dispensed through the second nozzle, and at least one of the following:
• the sensed vehicle travel speed, the sensed vehicle travel direction, the sensed wind speed, the sensed wind direction, and the sensed height of the second nozzle from the ground surface;
• determining, with the processor, an overlap region between the first spray pattern and the second spray pattern;
• comparing, with the processor, the determined overlap region with a pre-determined overlap;
• taking corrective action automatically by performing at least one of the following actions with the processor:
• changing the vehicle travel speed, changing a duration of time the fluids or fine granular particles are dispensed from at least one of the first nozzle and the second nozzle, adjusting a pointing direction of at least one of the first and second spray nozzles, and turning off at least one of the first and second spray nozzles;
• storing at least two weather correction factors in a memory look-up table;
• measuring at least two weather values associated with the weather correction factors;
• and
• determining, with the processor, a velocity of spray droplets at extremities of a stationary spray release cone based upon the stored weather correction factors and the measured weather values.
