Example 1.3.2 A domestic oven has a heat transfer surface area of 1.5m². If the temperature inside the oven is maintained at 200°C when the ambient temperature is 20° C, calculate the heat lost from the oven. Assume the walls of the oven to consist of an outside steel skin of 1.6mm thickness, insulation of 25mm thickness and an inner steel skin of 2mm thickness. Take the values of thermal conductivity as k(steel) = 40W/mK, k(insulation) = 0.05 W/mK. Take the convective heat transfer coefficient on the inside and outside surfaces to be 10W/m²K
