Question
1-A wall 1 ft thick and infinite in other direction has an initial uniform temperature (T;) of 100°F.
The surface temperature (Ts) at the two sides are suddenly increased and maintened at 300°F. The
wall is composed of nickel steel with a diffusivity of a 0.1 ft²/h. Compute the temperature
=
distribution within the wall as a function of time. Two sets of step sizes are to be used
1- Ax =0.05, At = 0.01
2- Ax =0.05, At = 0.0
X=O
X=L
