(20%), A long 20-cm-diameter cylindrical shaft made of stainless steel
8000k(g)/(m^(3)), and C_(p)=500(J)/(k)g-K 600\deg C.
The shaft is then allowed to cool slowly in an environment chamber at 200\deg C with an
average heat transfer coefficient of 100(W)/(m^(2))-K. Determine the temperature at the center
and the surface of the shaft 50 minutes after the start of the cooling process and also
determine the heat transfer per unit length of the shaft during this time period by using (a)
one term approximation and (b) the Heisler charts.
