Summary

A restricted inlet reduces the effective outlet capacity in Cooper’s natural-venting model. Based on Cooper (2002), p. 3-225.

Original illustration for Aerodynamic free area, level 3 Advanced.

Source basis: Cooper (2002), p. 3-225, Equation 22; redraw, do not copy Figure 3-9.6.
Alt text: Curve showing outlet effectiveness increasing as the inlet area grows relative to the outlet.
Accuracy notes: This correction describes inlet restriction, not the discharge coefficient of an individual vent. Temperatures are absolute.
