can sombody please help me, im a high school student and i really need help on this question
The diagram below show a cross-section view of a sheet of metal (of thermal conductivity, k) covered on each side by a layer of plastic of thermal conductivity k/1000. The lower face of the plastic is maintained at a steady temperature, T4 = 150°C. The top surface is maintained at a steady temperature, T1 = 20°C. Calculate the temperatures of the surfaces of the metal, T2 and T3. Assume that the heat lost through the sides of the metal (and plastic) is negligible.
i think I'v attacked the diagram
if anyone can, it would be really appriciated
