A large plane wall has a thickness L=50 cm and thermal conductivity k = 25 W/m. K. On the left surface (x = 0), it is subjected to a uniform heat flux q_0 while the surface temperature T_0 is constant. On the right surface, it experiences convection and radiation heat transfer while the surface temperature is T_6 =225 degree C and the surroanding temperature is 25 degree C. The emissivity and the convection heat transfer coefficient on the right surface are 0.7 and 15 W/m^2. K, respectively, (a) Obtain the variation of temperature in the wall (T(x) in terms of Also determine the value of heat flux (q_n) and the temperature of the left surface of the wall (at x = 0)
