Q3: A slab of thickness 15 cm initially at 30°C is exposed on one side to gases at 600°C with a convective heat transfer coefficient of 65W/m²K. The other side is insulated. Using the following property values determine the temperatures at both surfaces and the center plane after 20 minutes, density: 3550 kg/m³, sp. heat 586 J/kg.K, conductivity 19.5 W/m.K. Also calculate the heat flow up to the time into the solid. = =
