square plate heater (size 15 cm x 15 cm) is inserted between two slabs. Slab A is 2 cm thick (k = 50 W/mK) and slab B is 1cm thick (k = 0.2 W/mK). The outside heat transfer coefficient on both sides of A and B are 200 W/m2K and 50 W/m2K respectively. The temperature of surrounding air is 25°C. If the rating of heater is 1 kW, find. (i)Maximum temperature in the system (ii)Outer surface temperature of two slabs.
