1. A solid brick wall of thickness L = 10 cm, is insulated on one side and heated by convection on the other side. The initial temperature of the wall is 10C. Hot air at 200C from a fire over the surface of the wall with a heat transfer coefficient of 55 W/m2 C. What will the temperature be at the insulated side after 6.5 hours? Use thermal conductivity of wall as 0.2 W/mC and thermal diffusivity a = 8.7 x 10-7 m/s. L X h = 55 W/mC T = 200C
