Two parallel planes measuring 1.2 x 1.2 m apart by a distance of 4 cm. The emissivities of the planes are 0.4 and 0.6 respectively and the temperatures are 760 and 300oC, respectively. A radiation shield measuring 1.2 x 1.2 m and having an emissivity of 0.05 and a temperature of 500oC is placed midway between the two planes. Calculate the heat transfer rate of the two planes if there is no shield!
