2. Consider a large uranium plate of thickness 5cm and thermal conductivity k=28W/mK in which heat is generated uniformly at a constant rate of qG=5106W/m3. The left side of the plate is held at a constant temperature of 100C while the right side is held at a temperature of 150C. Considering six equally spaced nodes with a nodal spacing of 1cm : a) Obtain the finite difference formulation of this problem. b) Determine the nodal temperatures under steady state conditions by solving those equations. c) Plot the temperature as a function of position.** (** use Excel and add the matrix solution and graph as a separate sheet in your file)
