Summary

Air leakage through the gap of a closed door against the pressure difference, for gap areas of 0.01 m² and 0.024 m². Based on Klote (2002), pp. 4-280 and 4-288.

Original vector illustration for Stair pressurisation, level 2 Intermediate.

Source basis: Klote (2002), p. 4-280 (Eq. 5a), pp. 4-280 to 4-281 (door with 0.01 m² crack), p. 4-288 (door gap 0.024 m²)
Alt text: Line chart: airflow through a door gap against pressure difference, two rising curves that flatten, for gaps of 0.01 and 0.024 square metres.
