Read captions for more details👇 . The stack effect in the context of fires operates on the same principles as water flowing through a pipe, but with air moving up a chimney or through a building. When a fire heats the air, this hot air becomes less dense and rises, creating a draft. This upward movement of hot air creates negative pressure at the base, drawing in cooler air from outside to feed the fire with more oxygen. As the fire grows hotter, the draft becomes stronger, pulling in even more

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

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

SB Media on Instagram: "Unlike forced ventilation (fans...), the Stack Effect relies solely on buoyancy forces from heated air. As warm combustion gases rise, they reduce pressure at the chimney base, drawing in fresh air to sustain combustion while expelling exhaust upward. The effect lays its principle on hydrostatic pressure imbalance: • Hot air inside the chimney becomes less dense, creating an upward buoyant force. • The pressure differential drives flow, with taller chimneys enhancing the
