Consider a problem consisting of two diffusely emitting and reflecting parallel plates that are of infinite length into and out of the cross-section shown below. The lower plate has uniform

temperature T1 = 1000 K, and the upper plate has uniform temperature T2 = 500 K.The surroundings have a temperature of Te = 300 K. Surface 1 has gray emissivity ɛ = 0.8and surface 2 has gray emissivity e2 = 0.2 1.Find the average net radiative heat rate per unit length q: and q2 (W/m] on surfaces 1 and 2 assuming uniform radiation over each surface. Partition each of the two parallel plates into four equal segments (lower:1,2,3,4; upper: 6,7,8,9). Find the net radiative heat rate per unit length (q in W/m) for each segment, assuming uniform irradiation on each segment individually. Partition each of the two parallel plates into twenty equal segments (lower:3.1,2,3.20; upper: 22,22,23,.41). Find the net radiative heat rate per unit length (q inW/m) for each segment, assuming uniform irradiation on each segment individually. Plot these results and the results of questions 1 and 2 on the same graph. Submit a printout ofthe source code with your solution.
