Example 18-2 A very long enclosure is formed in the shape of an equilateral triangle, as shown. Two walls are held at constant temperature and the third wall is insulated. Determine the temperature of the insulated wall. The length of each side is 1 m. Solution: Do the calculation for a one meter depth, so that all areas equal 1 m 2 . The surface resistances to radiation are () ( ) 1 1 11 1 10 . 9 0.111 . 9 R A ε == = 2 2 22 0 . 6 0.6667 . 6 R A −− = 3 3 33 1 0 R A = The space resistance to radiation is 1 ij ii j R A F = Because of the symmetry of the problem,
