|---|---|---|---|---|---|---|---|---|---|---|---|
| perpendicular_surfaces | perp_rect_common_edge_H1W1 | H=W=1 (square plates equal to common edge length): F12≈0.200. 3D perpendicular rectangle formula from Incropera Table 13.1. | Complex formula per Incropera 7th Ed. Table 13.1 Case 5; H=h/c W=w/c where c=common edge length | Two perpendicular rectangles sharing a common edge; H=h/L_edge=1.0 W=w/L_edge=1.0 | H_ratio | 1 | W_ratio | 1 | Rectangle A1 (height h) | Rectangle A2 (width w) | 0.2 |
| perpendicular_surfaces | perp_rect_common_edge_H1W2 | H=1.0 W=2.0: F12≈0.276 from Incropera Fig 13.4 and Table 13.1 formula. | Complex formula; H=1 W=2 | Two perpendicular rectangles with common edge; H=1.0 W=2.0 | H_ratio | 1 | W_ratio | 2 | Rectangle A1 | Rectangle A2 | 0.276 |
