The 5-mm-thick bottom of a 200-mm-diameter pan may be made from aluminum (k = 240 W/m. K)
Question:
The 5-mm-thick bottom of a 200-mm-diameter pan may be made from aluminum (k = 240 W/m. K) or copper (k = 390 W/m. K). When used to boil water, the surface of the bottom exposed to the water is nominally at 110°C. If heat is transferred from the stove to the pan at a rate of 600 W, what is the temperature of the surface in contact with the stove for each of the two materials?
