A solar collector consists of a long duct through which air is blown; its cross section forms an equilateral triangle 1 m on a side. One side consists of a glass cover of emissivity Ej = 0.9, while the other two sides are absorber plates with €2 = E3 = 1.0. Glass cover E2, 72 fi, T. -Absorber plates Ez, Tz - During operation the surface temperatures are known to be T = 25°C, T2 = 45°C, and T3 = 70°C. What is the net rate at which radiation is transferred to the cover due to exchange with the absorber plates, in W/m? qi = i W/m
