Summary

Vent area for a 4 m × 4 m × 3 m room from the Swift-Epstein equation, for three fuel constants, against the pressure the room can withstand. Horizontal lines show the area of one wall and of the roof. Based on Zalosh (2002), p. 3-416.

Original illustration for Explosion venting, level 4 Expert.

Source basis: Zalosh (2002), p. 3-416 (Equation 12, range of applicability, Table 3-16.5, Example 8)
Alt text: Three falling curves of vent area against reduced pressure for ammonia, methane and propane-like gases, with lines for the wall and roof areas.
