Consider a slab of face area a and thickness l. suppose that l = 33 cm, a = 55 cm2, and the material is copper. if the faces of the slab are maintained at temperatures th = 129°c and tc = 21°c, and a steady state is reached, find the conduction rate through the slab. the thermal conductivity of copper is 401 w/m·k.
