Nozzles and spray quality
You raise the working pressure on a flat fan nozzle. What happens to the droplets?
Correct: They get smaller. As pressure increases, droplet size decreases (Farm Advisory Service note). Smaller droplets give more leaf cover but less penetration into the crop, and a higher drift risk. Lower pressures give bigger droplets that drift less.
Speed, nozzle output, application volume and how much product to put in the tank, each worked through step by step.
You plan an application volume of 200 L/ha. You will drive at 12 km/h with nozzles 0.5 m apart. What output does each nozzle need, in litres per minute (L/min)?
Correct: 2.00 L/min. Nozzle output (L/min) = rate (L/ha) × speed (km/h) × nozzle spacing (m) ÷ 600. So 200 × 12 × 0.5 ÷ 600 = 2.00 L/min. This is the formula on the National Sprayer Testing Scheme operator check sheet.

The City & Guilds assessment is a practical observation with oral questions, one to one with an independent assessor. There is no written test.
That is why Acrestep has no mock exam and no pass mark. It helps you revise the knowledge behind the questions and practise the calculations. It does not replace practice on a real sprayer with your trainer.
Acrestep is an independent revision aid. It is not the real assessment and is not affiliated with, or endorsed by, City & Guilds, NPTC or Lantra. Every question is written by us from public sources.
