2. Consider a large plane wall L=0.2 m, thermal conductivity k= 1.2 W/mK and surface area A= 15 m2. The two sides of the wall are maintained at constant temperatures of T1= 120 °C and T2= 50 °C. Determine; (50points) a. The variation of temperature within the wall and value of temperature at x=0.1m? b. The rate of heat conduction through the wall under steady condition with no heat generation? 2. Consider a large plane wall L=0.2 m, thermal conductivity k= 1.2 W/mK and surface area A= 15 m2.
