2.36 WP As shown in Fig. P2.36, an oven wall consists of a 0.635-cm-thick layer of steel (x, = 15.1 W/m · K) and a layer of brick (K = 0.72 W/m · K). At steady state, a temperature decrease of 0.7°C occurs over the steel layer. The inner temperature of the steel layer is 300°C. If the temperature of the outer surface of the brick must be no greater than 40°C, determine the thickness of brick, in cm, that ensures this limit is met.

In a kitchen there are two identical pots that have been previously heated, one of the pans is filled with 500ml of Water at 100◦C and the other with 500 no of oil at 130◦C. After that, there is more fire that continues to introduce heat to both liquids. In that instant, a person who had cut 300 g of potato into small cubes at a temperature of 25◦C, decides to pour half the amount of potato in boiling water and the other half in burning oil. Knowing that Water density is the 1.00 g / ml; the oil density = 0.87 g / ml; theSpecific heat of water = 4186 J/ kg ·◦C, is theOil specific heat = 2000 J/ kg ·◦C is thePotato specific heat = 5530 J /kg ·◦C (a) Determine the temperature of the thermal equilibrium between the potatoes in water, and the same portion in oil, considering each cases as isolated systems.
