If your sprayer output is 15 GPA at 5 mph, what must you do to double your output?

To double the output of a sprayer that is currently delivering 15 gallons per acre (GPA) at a speed of 5 miles per hour (mph), you would need to decrease the speed of travel. When you reduce the speed, the sprayer applies the same amount of pesticide over a smaller area in a given time, effectively increasing the amount applied per acre and thereby doubling the sprayer's output.

In a practical sense, if you lower your speed, you spend more time over the same area, allowing for more product to be deposited on the crops or surface being treated. This is based on the principle that application rate is influenced by both speed and volume—by decreasing speed while maintaining the same pressure and nozzle size, the total volume applied in a specific time frame increases.

The other options, while related to sprayer operation, would not directly lead to doubling the output in this scenario. Modifying the pressure to the nozzles could alter the droplet size or the pattern of the spray but would not directly double the output unless adjusted very specifically with that intention. Changing the nozzle size can also impact the output but may not lead to a precise doubling of the delivered volume unless the new nozzles are designed for that specific output
