Question: Three thin sheets of polished aluminum are placed parallel to each other so that the distance between them is very small compared to the size

Three thin sheets of polished aluminum are placed parallel to each other so that the distance between them is very small compared to the size of the sheets. If one of the outer sheets is at 280?C, and the other outer sheet is at 60?C, calculate the temperature of the intermediate sheet and the net rate of heat flow by radiation. Convection may be ignored.GIVENThree thin sheets of polished aluminum parallel to each otherThe distance between the sheets is small compared to the size of the sheetsOuter sheet temperaturesT1 = 280?C = 553 KT2 = 60?C = 333 KConvection may be ignoredASSUMPTIONSSteady stateAll surfaces aregray
