A cylindrical spine used as a fin to enhance the rate of

heat transfer from a surface. Our goal is to find the one-dimensional

temperature distribution in the spine. Write the conservation equation of

energy for the control volume shown in the figure. Show that temperature at

every location on this fin and at every time is found from the solution to:

where _ = T(x, t) Tf, a = _c/k, mc

= (Phc/_Ac) 0.5, and mr = (Phr/_Ac)

0.5. In these relations, hc is the heat transfer

coefficient for heat transfer by convection, and hr is the heat transfer

coefficient for heat transfer by radiation.
