When calibrating a broadcast sprayer, you find that the average nozzle output is 25 ounces for the recorded travel time. What is the spray rate in gallons per acre?

• A. 35 GPA
• B. 30 GPA
• C. 25 GPA
• D. 40 GPA

Answer: (C)

To determine the spray rate in gallons per acre (GPA), you can use the nozzle output and other calibration parameters. The conversion from ounces to gallons is important, as there are 128 ounces in a gallon. Therefore, if the average nozzle output is 25 ounces, you convert this figure to gallons by dividing by 128.

Once the conversion is made:

25 ounces ÷ 128 ounces/gallon = 0.1953125 gallons

After this conversion, it's crucial to know the total area covered, which is typically considered per acre when calculating GPA. In broadcast spraying, the spray rate can often be calculated using the formula (GPA = total output in gallons per acre).

In context, if you continue with the understanding that 0.1953125 gallons is output for a calculated number of acres (assuming a standard calibration that would represent the total output over one acre), the output would round to 25 GPA, as per the average nozzle output given for the calculation.

Thus, the correct answer is 25 GPA, which reflects the nozzle output converted effectively and aligned with the broadcasting practices typically used in agriculture. The expectation in the question format would therefore indicate that the final answer, relying purely on that straightforward calculation, results directly
