A circular fin (k = 240 W/m K) of uniform cross section, with diameter of 10

Question:

A circular fin (k = 240 W/m · K) of uniform cross section, with diameter of 10 mm and length of 50 mm, is attached to a wall with surface temperature of 350°C. The fin tip has a temperature of 200°C, and it is exposed to ambient air condition of 25°C and the convection heat transfer coefficient is 250 W/m· K. Assume steady one-dimensional heat transfer along the fin and the nodal spacing to be uniformly 10 mm,
(a) Using the energy balance approach, obtain the finite difference equations to determine the nodal temperatures, and
(b) Determine the nodal temperatures along the fin by solving those equations and compare the results with the analytical solution.
