Is unsteady-state like time travel?

Problems for Submission:

P1. Consider heat conduction through the walls of a pipe when the inside wall temperature is 200^oC and the outside wall temperature is 80^oC and the thickness of the wall is 0.05 m. The inside radius (r₀) is 0.05m and the outside radius is 0.1m. The differential equation that describes the temperature distribution is

Apply a finite difference representation of the derivatives of T with respect to r to obtain a set of linear equations which can be solved for the temperature as a function of radial position in the pipe wall.
