which answer would it be?

Consider a steel pan used to boil water (Twater 100 oC) on top of a stove. The bottom section of the pan is L thick and has a diameter of D. The stove produces Q Watts of heat when the burner is turned on. Heat transfer from the pan to the water is by convection with a heat transfer coefficient of h. Assume constant thermal conductivity and one- dimensional heat transfer and that the coordinate system is placed at the center of the bottom surface of the pan. Which of the following is a correct expression of the boundary condition between the pan and the water? O OT(0) O OT(L) O T(L)- T Water O OT(0) h (TO) water Water OT(L) h (TOL) water O (L) T x (D/2) 2

Solution

The option marked blue is correct i.e. 6th option. 7th option is also correct. pan bottom working as boundary so

heat transfer by conduction = heat transfer by convection
