Discuss the below in detail:
Q: A steady-state, finite-difference analysis has been performed on a cylindrical fin with a diameter of 12 mm and a thermal conductivity of 15 W/m · K. The convection process is characterized by a fluid temperature of 25°C and a heat transfer coefficient of 25 W/m2 · K.
(a) The temperatures for the first three nodes, separated by a spatial increment of x = 10 mm, are given in the sketch. Determine the fin heat rate.
(b) Determine the temperature at node 3, T3.
