question

Consider a double layered wall. Theemissivitiesof the outer andinner layer are 0.85 and 0.46, respectively. The ambient temperatureis 110°F and the temperature inside the room is 60°F.Calculate the radiant heat flux per unit area. Also, calculatethe radiant heat flux when an aluminium radiation shieldhaving\epsilon_s= 0.05 is used.
