2. In a cassava processing factory, the operator is shielded from the heat of the oven by a 20cm thick wall of solid brick. The oven wall has a surface area 1.7m². If the heat conducted is measured to be 1020W, calculate the temperature inside the oven. Assume thermal conductivity of the brick to be 0.1W/m.K and the outside temperature of the wall is 30°C. Ans: 150°C W​
