Problem 4.9: Consider heat transfer in a plane wall of total thickness L. The left surface is maintained at temperature T0 and the right surface is exposed to ambient temperature with heat transfer coefficient Determine the temperature distribution in the wall and heat input at the left surface of the wall for the following data: Solve for nodal temperatures and the heat at the left wall using (a) two linear finite elements and (b) one quadratic element.
