The composite strip in Figure P3-55 is exposed to the convection environment at 300ºC and h = 40 W/m2 · ºC. The material properties are kA = 20 W/m· ºC, kB = 1.2 W/m· ºC, and kC = 0.5 W/m· ºC. The strip is mounted on a plate maintained at the constant temperature of 50ºC. Calculate the heat transfer from the strip to plate per unit length of strip. Assume two-dimensional heat flow.
