Question:
Consider the perpendicular rectangles shown schematically.
(a) Determine the shape factor F12.
(b) For rectangle widths of X = 0.5, 1.5, and 5 m, plot F12 as a function of Zb for 0.05 Zb 0.4m. Compare your results with the view factor obtained from the two-dimensional relation for perpendicular plates with a common edge (Table).
