Question

The room is 20 ft by 20 ft wide and 9 ft high. The floor is at 100°F, the walls are at 60°F, and the ceiling is at 40°F. All surfaces are assumed to be black. Calculate the net radiation heat transfer (a) from the floor to the walls and (b) from the floor to the ceiling.

Step 1

Given: Length of room (L) = 20 ft Width of room (W) = 20 ft Height of room (H) = 9 ft Calculate the ratio L/(L+W): L/(L+W) = 20/(20+20) = 20/40 = 0.5 Calculate the view factor (F) from the floor to the walls using the formula: F = 4*(L/(L+W)) = 4*0.5 = 2 Show more…
