Consider a large plane wall of thickness L = 0.4 m, thermal conductivity k=2.3 W/m °C, and surface area A= 20 m2. The left side of the wall at x= 0 is subjected of T1 = 80°C. while the right side losses heated by convection to the surrounding air at T∞=15 oC with a heat transfer coefficient of h=24 W/m2 oC . Assuming constant thermal conductivity and no heat generation in the wall, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the wall, (b) obtain a relation for the variation of temperature in the wall by solving the differential equation, and (c) evaluate the rate of heat transfer through the wall

Question
Consider a large plane wall of thickness L = 0.4 m, thermal conductivity k=2.3 W/m °C, and surface area A= 20 m2. The left side of the wall at x= 0 is subjected of T1 = 80°C. while the right side losses heated by convection to the surrounding air at T∞=15 oC with a heat transfer coefficient of h=24 W/m2 oC . Assuming constant thermal conductivity and no heat
generation in the wall, (a) express the differential equation and the boundary conditions for
steady one-dimensional heat conduction through the wall, (b) obtain a relation for the
variation of temperature in the wall by solving the differential equation, and (c) evaluate the
rate of heat transfer through the wall
