1. Consider a large plane wall of thickness L = 0.2 m, thermal conductivity k = 1.2 W/m.C, and the surface area A = 15 m2. The two sides of the wall are maintained at constant temperatures of T1 = 120C and T2 = 50C, respectively. Do the following: (a) Find temperature distribution equation with heat generation of 50 W/m? (b) Sketch the temperature profile in the wall (c) The value of temperature at x = 0.1 m and x = 0.15 m. (d) Find both q and heat flux at x = 0.1 m and x =
