Two parallel plates 0.5 m by 1.0 m are spaced 150 mm apart. One plate is maintained at 1,000 C and the other at 500 C. The emissivities of the plates are 0.20 and 0.50, respectively. The plates exchange heat with each other and only the plate surfaces facing each other are to be considered in the analysis. Find the net heat transfer rate to each other. Neglect other modes of heat transfer (conduction and convection). View Factor is based on the case shown below:
