Dimensions of a room or compartment (simple case)
cibse_guide_e_chapter_6_appendix_simplecaseRelevant compartment dimensions for the simple case, which is a compartment with a single opening. These dimensions are then used in empirical correlations to predict fire dynamics
Equations
Input | Compartment dimensions
A_f = w_1 \cdot w_2
Input | Opening dimensions
A_o = w_o \cdot h_o
Input | Internal surface area
A_{net} = 2 \cdot A_f + 2 \cdot h (w_1 + w_2) - A_o
Input | Ratio of opening width to opening depth
d/w = w_2 / w_1
