What is the spray rate per gallon per acre if the average nozzle output is 25 ounces for the recorded travel time?

To determine the spray rate per gallon per acre, you need to first understand how to convert the output from ounces to gallons and relate that to the area being covered, which is one acre in this case.

The average nozzle output given is 25 ounces. There are 128 ounces in a gallon, so to find out how many gallons are represented by 25 ounces, you divide the output by the number of ounces per gallon:

25 ounces / 128 ounces per gallon = 0.1953 gallons.

To express the output in terms of an acre rate, you would typically consider how long it takes to cover one acre, and if the average output is based on that coverage.

In the context of the question and with the calculation applied, if the output per nozzle is adequate to cover an acre with a certain efficiency, then the spray rate can be interpolated directly into a per-acre rate. In this example, if the average output of the nozzles and the travel time correlates with a standard coverage, it leads to a total spray rate of 25 gallons per acre as calculated based on efficiency expectations, coverage area, and the nozzle output.

Thus, the correct answer of 25 gallons per acre reflects a common and reasonable estimator
