Figure Q5 shows a rectangular slab of 12 cm length and 4 cm high with the thermal conductivity of 10 W/m K. The top side of the slab is surrounding by a fluid at the temperature of T 600 K. The temperature boundaries of the other slab sides are shown in Figure Q5. The system can be assumed to operate with two-dimensional steady-state heat transfer (i.e. assume unit depth in the "z" direction). The heat transfer coefficient at the fluid/solid interface is 20 W/m2.K. (a) Apply Finite Difference Method to develop a set of two-dimensional finite-difference equations for calculations of the steady-state temperatures at the points "1", "2", "3" and "4", respectively.
