David Adeosun on Instagram: "Sooo the stack effect in a fire occurs when hot air rises in a building, creating a pressure difference which pulls cooler air from lower floors. This airflow acts like a chimney, rapidly spreading smoke, heat, and fire upwards through vertical spaces like stairwells or shafts. In tall buildings, this effect is more pronounced, making evacuation difficult and intensifying the fire's spread. Fire safety designs must account for this to prevent uncontrolled fire moveme

UNIVERSE | SCIENCE | TECHNOLOGY on Instagram: "a chimney works using principles of convection and air pressure, often called the stack effect. The Mechanics of a Chimney Hot Air Rises: The fire within a fireplace heats the air and gases, making them less dense than the surrounding cooler air. This natural buoyancy causes the hot air to rise up the vertical chimney passage. Pressure Difference (Draft): As the hot air and smoke rise and exit the top, a low-pressure zone is created at the base of t

UNIVERSE | SCIENCE | TECHNOLOGY on Instagram: "This is how a Chimney works 🏭🔥 A chimney works on a simple but powerful principle called the stack effect. When fuel burns, it produces hot gases and smoke. These gases are lighter than the surrounding cool air, so they naturally rise upward. The tall structure of a chimney creates a pressure difference: hot air inside moves up, while cooler air gets pulled in from below to feed the fire. This continuous airflow safely carries smoke, toxic gases,

Maritime Safety Training | STCW USCG MCA Certs | Resolve Academy on Instagram: "The reverse stack effect in the context of fire smoke movement refers to a situation where smoke moves downward instead of rising — which is the opposite of what we normally expect due to the stack effect. What is Reverse Stack Effect? Reverse stack effect happens when the outside air is warmer than the air inside the building (usually in tall buildings during hot weather or at night when A/C is running). This causes
