- 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?The tip of a soldering iron consists of a 0.6-cm- diameter copper rod, 7.6 cm long. If the tip must be 204C, what are the required minimum temperature of the base and the heat flow, in watts, into the base? Assume that h=22.7W/m2KandTair=21C.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.
- 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.2.44 To determine the thermal conductivity of a long, solid 2.5-cm-diameter rod, one half of the rod was inserted into a furnace while the other half was projecting into air at . After steady state had been reached, the temperatures at two points 7.6 cm apart were measured and found to be and , respectively. The heat transfer coefficient over the surface of the rod exposed to the air was estimated to be 22.7 . What is thermal conductivity of the rod?54. As shown in the figure, to dissipate heat from an electrical appliance, thin plates of metal with a thermal conductivity of 10 Btu/h·ft·F are used. Find the number of the plates to dissipate 10.55 W at steady state operation. Data: Tbase = 85 F, Tf = 65 F, h = 1 Btu/h·ft2·F, L = 10 in, b = 1 in, δ = 0.03 in. [Ans.: 15].
- Two volumes of air are separated by a thin rectangular heater (0.2 cm x 15 cm x 2 cm). The volumetric heat generation associated with the heater is 350 kW/m3. What is the temperature of the heater at steady state?The air in the bottom chamber is at (TB= 20 °C, hB= 15 W/m2.K) while the air in the top chamber is at (TT= 55 °C, hT= 9 W/m2K). hint: for such thin application, we shall assume the same surface temperature on both sides of the heater.An engineer receives a schematic fora reversible heat engine with three reservoirs at the temperatures shown to the right. The heat engine produces 1800 kW work as it pulls 3200 kW of heat from the 600K reservoir. The engineer wonders if the schematic is drawn correctly (in other words, are the arrows going the correct directions?) To answer this question, (a) calculate the heat interactions of the HE with the other two reservoirs. (b)If necessary, draw an updated diagram with the correct directionalities indicating the rates of heat transfer.A copper container of mass 0.080 kg and specific heat 387 Jkg-1 K-1 contains 0.30 kg of water and 0.040 kg of ice at 0˚C. Steam at 100˚C is passed into the water and its temperature stabilizes at 20.0˚C. Find the mass of the water left in the container. Assume the system is insulated from its environment.
- The initial temperature of a 50 cm long silver wire is 50 °C. The circumference of the wire in question is completely insulated, but both ends are kept at a temperature of 0 °C (zero degrees Celsius). Obtain the heat conduction along the wire as a function of time and position and, taking a single term in the solution, determine how many degrees Celsius the temperature in the middle of the rod will be after 7 minutes. (For silver wire, α=1.70 cm2/s.)What is non-equilibrium steady state? And what is the difference between non-equilibrium steady state and far from equilbrium condition?4) In an experiment to find the thermal conductivity, a metallic rod of diameter 25 mm is placed in a furnace such that its one half is inserted into the furnace and other half is projected out in a room at 300 K. Once the steady state reached, the temperatures measured between two points 76 mm apart were 399 K and 364 K, respectively. Taking a convection coefficient of 22.7 W/m 2 – K, find the thermal conductivity of the metal.
