THE PHYSICS OF A FIREBALL: THE BLEVE 💥 What you see in this video is a BLEVE (Boiling Liquid Expanding Vapor Explosion) involving an LPG truck. It is one of the most feared events in process engineering. ⚙️ How it Happens: Pressurization: A liquid (like propane) is kept under high pressure in a sealed tank, allowing it to stay liquid even above its boiling point. Structural Failure: Usually caused by external fire, the tank metal weakens and eventually tears. Instant Vaporization: When the tank
