Exam:

 1. How much liquid, in gallons per minute (GPM) do you need to collect from each nozzle to achieve an output of 20 GPA. Round off to nearest 3 decimal places.

2.  If a nozzle delivers 64 Ounces Per Minute (OPM), what is this in Gallons Per Minute (GPM)

3. If a nozzle delivers 0.35 Gallons Per Minute (GPM), what is this in Ounces Per Minute (OPM)? Round up or down and choose the most correct answer.

4. You want 30 GPA and have a nozzle spacing of  30”. By using a formula, you determine that you need to collect 1 GPM from each nozzle drive the field at 7 MPH. When you check the nozzles, the output is actually 1.5 GPM. What is your corrected field speed to achieve 30 GPA? Round to nearest whole number.

5.   A label mandates that you are to apply no more than 0.5 pounds of active ingredient (a.i.) per acre per season. There is 4 pounds of a.i. per gallon of formulation. How many pints of formulation is this per acre per season.
