A long, highly polished aluminum rod of diameter D = 35 mm is hung horizontally in a large room. The initial rod temperature is Ti = 90°C, and the room air is T∞ = 20°C. At time t1 = 1250 s, the rod temperature is T1 = 65°C, and, at time t2 = 6700 s, the rod temperature is T2 = 30°C. Determine the values of the constants C and n that appear in Equation 5.26. Plot the rod temperature versus time for 0 ≤ t ≤ 10,000 s. On the same graph, plot the rod temperature versus time for a constant value of the convection heat transfer coefficient, evaluated at a rod temperature of.
 For all cases, evaluate properties at ![]()
