A composite plane wall of A and B is shown in the figure below. Wall A has uniform volumetric heating at a rate of 1898 kW/m3 (note that the unit is kW) and to prevent any heat loss through the surface at x=0 a uniform heat flux is provided as shown (i.e., all the generated heat in wall A flows in +x direction and the temperature gradient at x=0 is zero). Wall B has no heat generation and its outer surface (x = LA+LB) is exposed to a fluid at 25°C with a convection heat transfer coefficient of h. All other relevant and ‘irrelevant’ values are given in the figure. If the thickness of wall A is LA = 62 mm and the temperature at the interface T2 = 180 °C, calculate the temperature T1 in °C.
