A triangular duct whose surfaces are all black has a length of L=0.69 m. By considering the details given below, calculate the total heat transfer rate by radiation from the bottom surface (Surface-1) to the other surfaces (Surface-2 and Surface-3) of the duct, in W. 0=5.67×10*8 W/(m²K*) L=1.13 m, T1=606 K L2=0.62 m, T2=433 K L3=0.84 m, T3=340 K
