Hydraulic & Spectrum State Sync

At 200 kPa pressure head across a 50m HDPE pipe with 20 drip emitters, a 1.5mm orifice leak at 18.5m generates a dominant turbulent acoustic noise peak at 425 Hz (-14.2 dB signal power at probe). Unintended water loss is 48.6 L/hr, resulting in 88.4% flow efficiency.
