📐 Key Calculations

Suspension Stability Index

SettlingTime / (Viscosity × ParticleSize^2)
Result: 12.8
Target > 10 for organic copper formulations

Abrasion Energy Index

MassFlow × Velocity^2 × HardnessFactor
Result: 2.4×10⁶ J/kg
Ceramic withstands up to 3.1×10⁶ J/kg

📊 Results

Nozzle replacement interval increased from 8 to 62 hours; copper usage reduced 19% while maintaining disease control efficacy; full audit pass for organic certification renewal
