Two very long concentric cylinders of diameters d1 = 0.42 m and d2 = 0.5 m are maintained at uniform temperatures of t1 = 950 k and t2 = 500 k and have emissivities ε1 = 1 and ε2 = 0.55, respectively. determine the net rate of radiation heat transfer between the two cylinders per unit length of the cylinders. (use σ = 5.67 × 10-8)
