Please solve 5.24.
5.23. The short cylindrical fin shown in Fig. P5.23 (O(R) = O(L)) is initially isothermal at temperature TSuddenly, it is exposed to a hot gas (h, T.). The fin base temperature is ht Tit = 0) - T TB h.T- Figure P5.23 Short cylindrical fin. 163 known (Ts) and constant. Obtain the temperature variation in the fin and the heat transfer rate through its base. 5.24. Re-solve Problem 5.23 for a short rectangular fin of cross section L x HOLL) 0(H)) as shown in Fig. P5.24. h.T. Set = 0) - TN h.T. H h.T. Figure P5.24 Short rectangular fin.
