During a sprayer calibration, if you collect 8 ounces of water in 15 seconds from a nozzle, what is the application rate in gallons per acre if the nozzle spacing is 20 inches?

To determine the application rate in gallons per acre from the collected amount of water, you can follow these steps:

First, convert the collected volume into gallons. Since there are 128 ounces in a gallon, 8 ounces of water can be converted as follows:

8 ounces ÷ 128 ounces/gallon = 0.0625 gallons

Next, determine the area being covered during the calibration. With a nozzle spacing of 20 inches, you need to convert the spacing into feet for ease of calculations:

20 inches ÷ 12 inches/foot = 1.67 feet

Now, calculate how many acres are covered in the time it took to collect the water. The flow rate is collected over 15 seconds. First, find out how many square feet are covered by the spray during this time. To do this, you can calculate the distance sprayed during those 15 seconds.

There are 60 seconds in a minute, so convert 15 seconds into minutes:

15 seconds = 0.25 minutes

If you're applying a spray with the nozzle spacing, this means 1 nozzle covers a strip:

(1.67 feet) x (0.25 minutes) = 0.4175 square feet

Now, to convert
