Leak Engineering Graduate Lecture 4-1 | Pneumatic-Acoustic Detection | Dr. Taekyung Kwon | ACTRI

ACTRI Graduate Lecture Series in Leak Engineering — Lecture 4-1. This lecture separates system-level pressure testing from acoustic localization in concealed-pipe investigation. It covers pressure-decay limits, compressible-flow reasoning, test boundaries, and evidence-based field decisions.
