A large flat steel plate is 2 cm thick.
If the initial temperatures (oC) within the plate are given, as a function of the distance from one face, by the equation
find the temperatures as a function of x and t if both faces are maintained at 0°C. Solve for the temperatures at t = 2.062 seconds.
Use the explicit method with x = 0.25 cm. Compare to the analytical solution
Guidance: consider the heat transfer only in the x direction and use where =0.000117 m2/s.
