A thin aluminum sheet with an emissivity of 0.38 on both sides is placed between two very large parallel plates, which are maintained at uniform temperatures T1 = 905 K and T2 = 650 K and have emissivities ε1 = 0.5 and ε2 = 0.8, respectively. Determine the net rate of radiation heat transfer between the two plates without the shield. (Please provide an answer before moving on to the next part.)
