Write the governing equation and boundary conditions for 1-D heat transfer in a concrete wall 25cm thick and thermal conductivity k=0.9W/mK. Consider Convective boundary condition on one side h=100W/m²K and Tfluid=298K of the wall and heat flux 1250W/m² on the other side. Consider heat flux to be leaving the wall (heat being removed from the wall at a certain rate). Consider heat generation 1x10⁴ W/m³ in the wall. Derive discretized equations for the above problem.

Develop a matlab code to solve the discretized equations and generate a representative T vs x plot to demonstrate that the code is functioning.
