Please help me with this revision question, explain step by step ,

A long concrete dam of triangular cross section has a thermal conductivity of 0.6W/m.K and whose cross section is shown in Figure Q2. The exposed surface is subjected to heat flux. qo=600W/m2 and to convection with the ambient air at 25C and a heat transfer coefficient of 40Wim2K. The 200cm high vertical section of the dam is exposed to convection with water at 15C and a heat transfer coefficient 160Wlm2.K. The 200cm long base is insulated. Figure Q2 Finite difference analysis is to be carried out using nodes as described with x=100cm and y=100cm a) Obtain the finite difference equations for steady two-dimensional heat transfer for nodes 1, 3 and 5 . List down the equations with only the temperatures as the variables. Do not attempt to solve the numerical values of the temperatures (15 marks) b) Node 5 is considered as an interior node. How can a node on an insulated boundary be treated as an interior node in the finite difference formulation of a plane wall? Explain your
