Ex.2.8. A plane wall 6.0cm thick generates heat internally at the rate of 0.3MW/m3. One side of the wall is insulated, and the other side is exposed to an environment at 93C. The convection heat-transfer coefficient between the wall and the environment is 570 W/(m2C). The thermal conductivity of the wall is 21W/(mC). Calculate the maximum temperature in the wall. (TB1, Problem 2.34) [Ans: 150.3C ]
