Textbook Question

Chapter 3, Problem 3.82P

A long rod of 60-mm diameter and thermophysical properties ρ = 8000 k g / m 3 , c = 500 J / k g ⋅ 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 / m 2 ⋅ K .

(a) What is the centerline temperature of the rod when the surface temperature is 550 K?

(b) In a heat-treating process, the centerline temperature of the rod must be increased from T i = 300 K to T = 500 K . Compute and plot the centerline temperature histories for h = 100 , 500 , and 1000 W / m 2 ⋅ K . In each case the calculation may be terminated when T = 500 K .
