CHAP 5 Finite Elements for Heat Transfer Problems 283 4. Determine the temperature distribution (nodal temperatures) of the structure shown in the figure using two equal–length, linear finite elements with the cross-sectional area of 1 m2. The thermal conductivity is 10 W/mºC. The left side is maintained at 300 ºC. The right side is subjected to heat loss by convection with h= 1 W/m2ºC and Tf= 30 ºC. All other sides are insulated.
