Short title	Smoke leaves through the upper doorway as cooler air enters through the lower part.
Image title	Cross-section of a fire room and a neighbouring room joined by an open doorway. In the fire room a deep hot smoke layer fills the upper part. The pressure difference across the doorway varies with height: above a neutral level smoke flows out, below it cooler fresh air flows in, with arrow lengths following the pressure profile. The outflowing smoke rises as a door jet into the neighbouring room, and the opposing flows mix where they meet.
