Question

A very long rod of 5 mm diameter and conductivity 25 W/m K is subjected to a heat

treatment process. A 30 mm long portion of the rod within the induction heating coil

experiences uniform volumetric heat generation of 7.5 × 106 W/m3

. The unheated

portions of the rod experience convection with the ambient air at 20 °C and h = 10

W/m2 K. Assume that there is no convection from the surface of the rod within the coil.

(a) Calculate the steady-state temperature To of the rod at the midpoint of the heated

portion in the coil. (b) Calculate the temperature of the rod Tb at the edge of the heated

portion.​
