Question: Consider the system of Problem 4.55. Initially with no flue gases flowing, the walls (a = 5.5 X 10-7 m2/s) are at a uniform temperature

Consider the system of Problem 4.55. Initially with no flue gases flowing, the walls (a = 5.5 X 10-7 m2/s) are at a uniform temperature of 25°C. Using the implicit, finite-difference method with a time increment of 1 h, find the temperature distribution in the wall 5, 10, 50, and 100 h after introduction of the flue gases.
