5. A steel post (10 mm diameter, 0.5 m length) is placed vertically on top of a heated block of steel (steel thermal conductivity 50 Wm K1) with perfect contact. The core temperature of the block is Th. However, placing the steel post on the block reduces the temperature at the interface between the post and the block to T 195 C, since the post acts as a fin (assume that it is infinitely long with respect to its diameter)...
