Why is it important to measure the distance between the nozzle and the target before spraying?

• A. It speeds up the job
• B. It ensures the nozzle spins evenly
• C. It affects the uniformity of the spray pattern in broadcast applications
• D. It is required by law

Answer: (C)

The main idea is that how far the nozzle is from the target governs how the spray lands on the surface. Nozzles produce a defined spray pattern with a specific angle, so the distance determines the width of that pattern when it reaches the target. At the right height, the pattern from adjacent passes overlaps enough to give even, uniform coverage across the whole area. If the nozzle is too close, you get a dense, concentrated patch and possible runoff or spotting. If it’s too far, the pattern becomes too broad and thin in places, creating gaps and increasing the chance of drift, which also means uneven application. In broadcast applications, uniformity across a large area is essential to ensure every part of the target receives the intended amount of product. Distance control helps achieve that consistent coverage. The other ideas—speeding up the job, the nozzle spinning evenly, or legal requirements—aren’t the core reason for measuring distance here. The key benefit is predictable, even distribution of the spray on the target.
