The figure below shows a multilayered plate to which heat is transferred. The thickness of each plate is LA=0.015m,LB=0.1m and LC=0.075m, and the thermal conductivity of each plate is kA=0.0151,kB=0.0433 and kC=0.762(Wm1K1). According to this; a. Calculate the heat flux through the plate if the inner surface T1=255K and the outer surface T4=298K. b. It is thought that the heat loss can be reduced by 50% by increasing the "LB" thickness of the B plate. Accordingly, what should the LB value be
