Question

Thanks!

A metal rod (krod) at steady state that has a total length of 2L = 100 mm is inserted into an insulated wall such that half of the rod (L) is in the insulated portion, and half of the rod (L) is exposed to an airstream of temperature T infinity and convection coefficient h. An electromagnetic field induces volumetric energy generation at a uniform rate of q. within the embedded portion of the rod. It can be assumed that the exposed region may be approximated as a very long fin. For the following properties T infinity = 20 degree C, h = 100 W/m2K, L = 50 mm, D = 5 mm, k = 25 W/mK, q. = 106 W/m3: Derive an expression for the temperature at the base, Tb in terms of the given variables. Compute the temperature at the base (Tb). Compute the temperature at the embedded end of the rod (To) What is Ttip?
