A long rod of 60-mm diameter and thermophysical properties p = 8000 kg/m³, c = 500 J/kg-K, and k = 50 W/m-K is initially at a uniform temperature and is heated in a forced convection furnace maintained at 750 K. The convection coefficient is estimated to be 1000 W/m².K. What is the centerline temperature of the rod when the surface temperature is 420 K? The centerline temperature of the rod is i K.

Question

 Assume the Fourier number, Fo, is greater than or equal to 0.2 (note that you still need to calculate the Biot number, and possibly a second Biot number).
