Unformatted text preview: ( ) y x T , numerically and plot the results. Question 2. A circular rod is 12 cm long and 2 cm in diameter. As shown on the sketch below, the rod is insulated on all surfaces and is initially at 15C. For t , the = x end is heated by an electrical device that inputs 20 watts of power to the rod. The temperature ( ) y x T , of the rod is governed by the 1-D diffusion equation subject to Neumann BCs at = x and cm x 12 = . Choose cm x 2 = and 5 = t seconds. Solve for ( ) y x T , numerically for 150 t seconds by applying each of : (i) the explicit scheme (ii) the fully implicit scheme (iii) Crank-Nicolson scheme Material properties of the rod are: C m W k = 200 , s m 2 5 10 5 = For comparison, plot T versus x at s t 150 = based on the results from (i), (ii), and (iii). 2 cm diameter...
