0,20 m 3.) A thick concrete wall is insulated on one side as shown. The wall 500 K is initially at 300 K. Suddenly the left side wall temperature is raised to 500 K and held constant. Neglect radiation. Given: p 2300 kg/m c 880 J/kg-K, k 1.4 W/m-K.: At t 0 T(x,0) 300 K a) At t 10 minutes find the heat flux at the wall left side, /A qx" Wim Plot (or carefully draw to scale the temperature distribution T vsx at time 3 minutes. W/m2. b) Att 4 hours find the heat flux at the wall left side, Q /A qx" Plot (or carefully draw to scale) the temperature distribution T vs X at time 4 hours. Show minimum Tvalue.
