A circular fin of uniform cross section, with diameter of 10m and length of 50mm, is attached to a wall with surface temperature of 350C. The fin is made of material with thermal conductivity of 240 w/mk and it is exposed to an ambient air condition of 25C and the convection heat transfer coefficient of 250 w/m2K. Assume steady one dimensional heat transfer along the fin. Solve for the temperature distribution using numerical approach. Define the nodal spacing to be uniformly 10mm and using the energy balance approach obtain the finite difference equation to determine the nodal temperature.
