During calibration, marking a 200 ft course serves to verify what?

• A. The swath width
• B. The nozzle pressure
• C. The travel speed
• D. The travel distance

Answer: (C)

Marking a measured course during calibration is all about pinning down how fast you’re moving. By driving the 200 ft course and timing how long it takes, you calculate travel speed (mph). That speed is critical because when you know the spray’s flow rate (gallons per minute) and the boom swath width, you use speed to convert that flow into gallons per acre. The 200 ft mark isn’t used to check how wide the spray will cover (swath width) or to verify nozzle pressure. It also isn’t about the total distance you travel as a check; it’s about turning a measured distance into a precise speed so the application rate can be calculated accurately. For example, if the 200 ft course is covered in 18 seconds, the speed is about 7.6 mph, which then feeds into the calculation to determine gallons per acre.
