Pipe Flowrate Measurement: Problem Solving

912
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...

Area of Science:

  • Environmental Science
  • Analytical Chemistry
  • Biotechnology

Background:

  • Microplastic (MP) pollution presents significant environmental and public health challenges.
  • Existing detection methods are often labor-intensive, complex, and unsuitable for rapid field analysis.
  • There is a critical need for efficient, portable, and real-time MP detection technologies.

Purpose of the Study:

  • To develop and validate a novel Machine learning (ML)-Integrated Droplet-based REal-time Analysis of MP (MiDREAM) system.
  • To enable high-throughput, accurate, and on-site detection of microplastics.
  • To provide a portable and integrated solution for environmental monitoring.

Main Methods:

  • Utilized a compact peristaltic pump for high-throughput droplet generation (> 200 Hz) encapsulating MPs.
  • Employed a high-resolution complementary metal oxide semiconductor (CMOS) sensor with an optimized YOLO v8 ML model for real-time analysis.
  • Validated performance against hemocytometer counting and surface-enhanced Raman spectroscopy (SERS).

Main Results:

  • Achieved high detection accuracy (>90%) and classification accuracy for various MP sizes (95.4% for 3 μm to 85.3% for 30 μm).
  • The YOLO v8 ML model demonstrated high performance with mAP of 0.982 and AUC of 97.64%.
  • Showcased superior performance compared to conventional methods with high correlation (R² = 0.9965) and minimal deviation (6.36%).

Conclusions:

  • The portable MiDREAM system provides a robust and accurate solution for real-time microplastic detection.
  • Demonstrated adaptability and high accuracy in real-world water samples and diverse environmental conditions.
  • Offers a promising advancement for efficient environmental monitoring and pollution assessment.
