Consider a large plane wall of thickness L= 0.3 m, thermal conductivity k= 2.5 W/m · K,and surface area  A= 12 m2. The leftside ofthe wall at x = 0 is subjected to a net heat flux of qo = 700 W/m2 while the temperature at that surface is measured to be T1= 80 °C. Assuming constant thermal conductivity and noheat generation in the wall, (a) express the differential equation and the boundary conditions for steady onedimensional heat conduction through the wall, (b) obtain a relation for the variation of temperature in thewall bysolving the differential equation, and (c) evaluate the temperature of the right surface ofthewall at x=L.Answer:(c) -4 °C
