- An aluminum bar has a cross-section that is 5.07 cm by 6.38 cm and is 1.53 m long. Aluminum has a thermal conductivity of 205 W/m K. If the aluminum bar is used to bridge between ice at 0 °C and boiling water at 100 °C, what is the rate of heat transfer (in W) along the bar?A cubical piece of heat-shield-tile from the space shuttle measures 0.19 m on a side and has a thermal conductivity of 0.065 J/(s-m.C°). The outer surface of the tile is heated to a temperature of 1160°C, while the inner surface is maintained at a temperature of 18°C. (a) How much heat flows from the outer to the inner surface of the tile in 5.0 minutes? (b) If this amount of heat were transferred to 1.7 liters (1.7 kg) of liquid water, by how many Celsius degrees would the temperature of the water rise? (a) Number i (b) Number i 7 Units Units Heat flowAn aluminum bar has a cross-section that is 4.31 cm by 7.32 cm and is 2.38 m long. Aluminum has a thermal conductivity of 205 W/m K. If the aluminum bar is used to bridge between ice at 0 °C and boiling water at 100 °C, what is the rate of heat transfer (in W) along the bar?
- A 12 m by 4.2 m concrete wall has the thickness 8.2 cm. Find the heating rate through this wall if one side of the wall is at 36 C and the other side is at 28°C. The thermal conductivity of this concrete wall is 1.0 W/m-K.The concrete slab of a basement is 11 m long and 8 m wide, and 0.20 m thick. During the winter, temperatures are nominally 17°C and 10°C at the top and bottom surfaces, respectively. If the concrete has a thermal conductivity of 1.4 W/mK, what is the rate of heat loss through the slab? If the basement is heated by a gas furnace operation at an efficiency of 90%, and natural gas is priced at $0.02. MJ, what is the daily cost of the heat loss. Answer: QLOSS = 4.312 kW, COST = $8.28/daySuppose a house's walls are 13.5 cm thick and and have an average thermal conductivity twice that of glass wool. Given: Thermal Conductivity of glass wool= 0.042k Calculate the rate of heat conduction, in watts, through the house's walls. Assume there are no windows or doors. The surface area of the walls is 120 m2 and their inside surface is at 16°C, while their outside surface is at 5.15°C .
