5-17 Consider steady heat conduction in a plane wall with variable heat generation and constant thermal conductivity. The nodal network of the medium consists of nodes 0,1,2,3, and 4 with a uniform nodal spacing of x. Using the energy balance approach, obtain the finite difference formulation of the boundary nodes for the case of uniform heat flux q0 at the left boundary (node 0 ) and convection at the right boundary (node 4) with a convection coefficient of h and an ambient temperature of T
