An infinitely long furnace of 0.5 m x 0.4 m cross-section is shown in the figure below. Consider all surfaces of the furnace to be black. The top and bottom walls are maintained at temperature T1 = T3 = 927oC while the side walls are at temperature T2 = T4 = 527oC. The view factor, F1-2 is 0.26. The net radiation heat loss or gain on side 1 is _____ W/m.
Stefan-Boltzman constant = 5.67 x 10-8 W/m2-K4
(Important - Enter only the numerical value in the answer) 
    Correct answer is '24530.688'. Can you explain this answer?
    Verified Answer
    An infinitely long furnace of 0.5 m x 0.4 m cross-section is shown in ...
    T1 = 927oC = 1200K,
    T2 = 527oC = 800K
    F12 = F14 = 0.26
    F11 + F12 + F13 + F14 = 1
    F13 = 0.48
    Q = Q12 + Q13 + Q14
    Q13 = 0 since the temperatures are same
    Q = Q12 + Q14 = 2×σb×A×F12(T14 - T24)
    = 24530.688 Watt
