- 2.2 A small dam, which is idealized by a large slab 1.2 m thick, is to be completely poured in a short Period of time. The hydration of the concrete results in the equivalent of a distributed source of constant strength of 100 W/m3. If both dam surfaces are at 16°C, determine the maximum temperature to which the concrete will be subjected, assuming steady-state conditions. The thermal conductivity of the wet concrete can be taken as 0.84 W/m K.A cylindrical liquid oxygen (LOX) tank has a diameter of 1.22 m, a length of 6.1 m, and hemispherical ends. The boiling point of LOX is -179.4C. An insulation is sought that will reduce the boil-off rate in the steady state to no more than 11.3 kg/h. The heat of vaporization of LOX is 214 kJ/kg. If the thickness of this insulation is to be no more than 7.5 cm, what would the value of its thermal conductivity have to be?3.2 High-strength steel is required for use in building structures and equipment (e.g., cranes). It is produced by heat treating quench-hardened steel in a process called tempering that reduces brittleness and imparts toughness. In a production facility, alloy steel plates (k = 50 W/m K, c = 460 J/kg K, and ρ = 7865 kg/m3) of thickness 3.0 cm have to be tempered in a convective oven by heating them to 550°C. If the plates are initially at 40°C and the air inside the heat treating oven is at 700°C with a convective heat transfer coefficient of 45 W/m2 K, determine how long the plate has to remain in the oven.
- 3.17 A 1.4-kg aluminum household iron has a 500-W heating element. The surface area is . The ambient temperature is 21°C, and the surface heat transfer coefficient is . How long after the iron is plugged in does its temperature reach 104°C?A plane wall, 7.5 cm thick, generates heat internally at the rate of 105 W/m3. One side of the wall is insulated, and the other side is exposed to an environment at 90C. The convection heat transfer coefficient between the wall and the environment is 500 W/m2 K. If the thermal conductivity of the wall is 12 W/m K, calculate the maximum temperature in the wall.Carbon steel cubes (side = 8 mm, ρ = 7833 kg/m3, k = 54 W/m·°C, Cp = 0.465 kJ/kg·°C, and α = 1.474x10-6 m2/s) are annealed by heating them first to 850°C in a furnace and then allowing them to cool slowly to 95°C in ambient air at 28°C. What is the total rate of heat transfer from the cubes to the ambient air, when 2700 cubes are to be annealed per hour (in Watts)?

If the common brick is 9 in., calculate the exit temperature.An ice chest is constructed of Styrofoam [k=0.033 W/(m.k)] with inside dimension of 25 by 40 by 100 cm. The wall thickness is 5.0 cm. The outside of the chest is exposed to air at 25 oC with h=10 W/m2oC. If the chest is completely filled with ice, calculate the time for the ice to completely melt. State your assumptions. The heat of fusion is 330 KJ/kg. Heat transfer through the wall joints maybe neglected.Solving Thermal Properties Related Problems Determine the amount of heat removed from 1.5 kg of bologna (sausage) when cooled from 24°C to -7°C.

- 10 kg of frozen chicken at an initial temperature of -20°C is to be thawed and raised to a temperature of 10°C before cooking. The freezing point of the meat is -1.7°C and the specific heats above and below the freezing point are 3.1 kJ/kg-K and 1.6 kJ/kg-K, respectively. The heat of fusion (the amount of heat needed per unit mass to thaw chicken at the freezing point) is 233 kJ/kg. Find the total amount of heat that must be transferred to complete this the process.Solar heating of a house is much more efficientif there is a way to store the thermal energy collected during theday to warm the house at night.
