Pipe Flowrate Measurement: Problem Solving

A spray tank system is engineered to uniformly distribute a pest-control liquid across plants by using a pressurized mechanism. The tank, pressurized to 150 kPa, holds the pesticide at a height of 0.80 meters. Liquid flows from the tank through a 1.9 meter pipe with a diameter of 0.015 meters, angled at 0.698 radians, ultimately reaching a 0.007 meter nozzle that sprays the pesticide. Accurate calculation of the system's flow rate is crucial to ensure uniform application, and this is achieved...

Summary

Reducing pesticide spray drift is crucial. Combining drift-reducing nozzles, adjusted nozzle height, and shielding significantly cuts off-target deposition, enhancing environmental safety in agricultural applications.

Area of Science:

  • Agricultural Engineering
  • Environmental Science
  • Pesticide Application Technology

Background:

  • Off-target pesticide spray drift poses environmental risks.
  • Knapsack spray applications require effective drift mitigation strategies.

Purpose of the Study:

  • To investigate the impact of drift-reducing nozzles, nozzle height, and nozzle shielding on spray drift deposition.
  • To compare field trial results with regulatory values for environmental risk assessments in the EU and UK.

Main Methods:

  • Combined modeling and experimental field trials.
  • Evaluation of drift deposition on standardized band spray scenarios.
  • Comparison of measured deposition with regulatory values for environmental risk assessments.

Main Results:

  • Nozzle height significantly influenced deposition on evaluation strips.
  • Drift-reducing nozzles met or exceeded their certified reduction class.
  • Nozzle shielding further reduced spray drift.
  • The combination of all three measures reduced deposition by up to 99% compared to the reference.

Conclusions:

  • Realistic drift deposition values were obtained for band spray scenarios.
  • The findings support refined risk assessments for spot or band pesticide applications.
  • The study provides higher-tier data for plant protection product authorization procedures in the EU and UK.
