The height of the cells for a finite-difference solution of the temperature, in the rectangular solid shown in Fig. P5-147 is one-half the cell width to improve the accuracy of the solution. If the left surface is exposed to air at To with a heat transfer coefficient of h, the correct finite-difference heat conduction energy balance for node 5 is
