= 2. A flat plate of a polymer (k = 1.1 W/m K) will be cured using microwave radiation. The plate has a thickness d = 5 cm and it is exposed to flowing air at a temperature To on both its top and bottom surfaces (see figure). The microwave radiation will be absorbed by the polymer at a uniform rate per unit volume Er.
