Determine the thermal conductivity, Mechanical Engineering

Assignment Help:

A rod of 80mm diameter and 10mm length with thermal conductivity 16W/m-deg protrudes from a surface at 160 oC. The rod is exposed to air at 30 oC with convective coefficient of 25W/m2deg. How does the heat flow from this rod get affected if the similar material volume is used for two fins of the same length? Consider short fin with end insulated.
