Two gray surfaces with emmissivities 81=0.8 and ɛr=0.5are located as shown in the figure. The temperature of the plate 1 Tr=500 K and temperature of the plate 2 is T2=900 K. Calculate the radiation heat transfer between the surfaces. Ignore the heat transfer between surfaces and the surrounding air.
