Options:

  • (A) 0.175
  • (B) 0.215
  • (C) 0.350
  • (D) 0.430

Official Answer Key:

A

Step-by-Step Solution & Explanation

Total swath = 16 × 0.5 = 8 m. Area covered per hour = swath(m) × speed(km/h) × 1000 = 8×3.5×1000 = 28,000 m²/h. Total spray volume/h = area × application rate/10,000 = 28,000×1/10,000 = 2.8 m³/h. Per nozzle = 2.8/16 = 0.175 m³/h.
