The base plate of a 800 w household iron has a thickness L = 0.6 cm, a surface area A = 400 cm, a thermal conductivity k = 60 W/m-K and an emissivity & = 0.6. The iron is left on the iron board with its base exposed to the air ( T = 20C). The convection heat transfer coefficient between the base surface and the surrounding air is h=35 W/mK.
