A metal rod with a length of 2.2m and a diameter of 13cm is made of a material with a thermal conductivity of 46.6Wm1K1. The rod is initially at a uniform temperature of 299K and is subjected to heat transfer from the surrounding air at a temperature of 314K. The heat transfer coefficient between the air and the rod is 13Wm2K1. What is the steady state temperature (in units of K ) at the center of the rod after sufficient time has passed? 428 margin of error +/2
