Please solve this problem THank you Two slabs sandwich a square plate heater of dimensions 30 cm by 30cm. One slab is 13 mm thick (k =0.67 W/m°C) while theother is 36 mm (k = 0.47 W/m°C). If the outside temperature of both slabs is 60°C, calculate the maximum temperature in thesystem. The rating of the heater is 2 kW. Write your answer to two decimal places.!!!3!

Given data: t1=13 mmk1=0.67 W/m°Ct2=36 mmk2=0.47 W/m°CTO=60°CQ=2 kW Need to determine the maximum…

The inside wall of a furnace is at 2100oF and the outside wall is at 300oF. The wall of a furnace must be designed to transmit no more than 220 Btu/hr-ft2. Two types of bricks are available for construction:TYPE A: k = 0.38 Btu/ hr-ft-R with an allowable maximum temperature of 1400oFTYPE B: k = 0.98 Btu/ hr-ft-R with an allowable maximum temperature of 2300oF Both types of bricks have the same dimensions (9” x 4.5” x 3”) but the cost for Type B brick is twice the cost of Type A brick. Illustrate the order of arrangement of bricks A and B in the furnace wall (with thickness, estimated temperatures at the interface between walls A and B and at the interior and exterior surface, the transport area and direction of transfer included)
