This is Heat Transfer problem. I couldnt figure it out although has been trying for 2 hours :(( Please help. Thanks a lots!

Some numerical answers provided in [brackets]. 1 Pin. Consider a fin with an insulated tip. The fin is made of copper (km = 400 W m‘l K“. It is cylindrical, with a diameterof 0.5 cm and a length of 8 cm. The base is maintained at 200 °C. Convection across the surface of the fin occurs withh = 125Wm‘2K“ and T.” = 40%. (a) Determine the temperature distribution within the fin. What is the temperature atx = L12 andx = L? [166 °C,144 °c] (b) Determine the heat rate dissipated by the fin. [16.9 W](c) Determine the effectiveness of the fin. [43](d) Determine the efficiency of the fin. [0.67] (e) Justify the assumption that fin cross-sections are at uniform temperature (cough this sounds like lumped ca-pacitance cough) 2 Transient Finite Difference For each of these conditions, assume a square grid (Ax = Ay), constant physical properties and convection charac-teristics. and nodes centered within interior elements and on the surface for exterior elements. - . 1 . . . . lib-bl. .
