-collector, L=10m LA₂ T₂=373 K, A₂= 15m² E₂=0.5 A'3 3=Tsur 300K င်း= | T₁= 973K, A₁-10m², E₁ = 0.9 tw=lm -Heater, L=10m a curved solar In manufacturing, the special coating on absorber of surface area Az=15m² is cured by exposing it to an infrared heater of width W=lm. The absorber and heater are both of length L=10m and are separated by a distance of H=0.60 m. The upper surface of the absorber and the lower surface of the heater are insulated. The heater is at T₁= 973K and has an emissivity of E=0.9, while the absorber is at T₂ = 373K and has an emissivity of E₂=0.5₁ The entire system is in a large room whose walls are at T3=300k. What is the net rate of heat transfer to the absorber surface. 1) find the heat transfer from surface 1. 2) find the heat transfer to surface 2. H= 0.6 m²
