Compute the heat flux thoroughly a 10 cm thick brick wall (k= 0.69 W/m-deg) Which has temperature of 105° C & 10° C maintained on its two faces. How this heat flux would vary when 3cm thick layers of magnesia insulation is added on the inside & outside faces of the wall?
Also determine the interface temperature for the composite wall.
