If 1700 ounces of material is collected from nozzles in 90 seconds, what is the total flow volume in gallons per minute?

To determine the total flow volume in gallons per minute, it is important to convert the collected material from ounces to gallons and then calculate the flow rate over time.

First, recall that there are 128 ounces in one gallon. Therefore, to convert 1700 ounces to gallons, you would divide by 128:

1700 ounces ÷ 128 ounces/gallon = 13.28125 gallons.

Next, since the material was collected over a period of 90 seconds, we need to convert that time frame into minutes, which means dividing 90 seconds by 60 seconds/minute:

90 seconds ÷ 60 seconds/minute = 1.5 minutes.

Now, to find the flow volume in gallons per minute, divide the total gallons by the time in minutes:

13.28125 gallons ÷ 1.5 minutes ≈ 8.85 gallons per minute.

This calculation yields approximately 8.85 gallons per minute, making the correct choice consistent with option C. The importance of knowing these conversions and calculations lies in their application in determining the efficiency and effectiveness of aerial application processes, where precise measurement is crucial.
