Discuss the modes of heat transfer that determine the equilibrium temperature of the space shuttle Endeavour when it is in orbit. What happens when it reenters the earths atmosphere?
Using the information in Problem 1.22, estimate the ambient air temperature that could cause frostbite on a calm day on the ski slopes. 1.22 In order to prevent frostbite to skiers on chair lifts, the weather report at most ski areas gives both an air temperature and the wind-chill temperature. The air temperature is measured with a thermometer that is not affected by the wind. However, the rate of heat loss from the skier increases with wind velocity, and the wind-chill temperature is the temperature that would result in the same rate of heat loss in still air as occurs at the measured air temperature with the existing wind. Suppose that the inner temperature of a 3-mm-thick layer of skin with a thermal conductivity of 0.35W/mKis35C and the air temperature is 20C. Under calm ambient conditions the heat transfer coefficient at the outer skin surface is about 20W/m2K (see Table 1.4), but in a 40-mph wind it increases to 75W/m2K. If frostbite occurs when the skin temperature drops to about 10C, do you advise the skier to wear a face mask? What is the skin temperature drop due to the wind?
A plane wall 15 cm thick has a thermal conductivity given by the relation k=2.0+0.0005T[W/mK] where T is in kelvin. If one surface of this wall is maintained at 150C and the other at 50C, determine the rate of heat transfer per square meter. Sketch the temperature distribution through the wall.

An open system is often referred to as control volume, which is a properly selected region in space in which mass and energy can flow across the boundaries as figure 1.2. The boundary of a open thermodynamic system is called the control surface Across the Boundaries E = Yes F 0 = Yes w =Yes Control surface ass YES W CONTROL VOLUME energy YES Figure 1.2. A cooling/heating radiator is an example of such a system – give two more examples of such a system.
5. An irregularly shaped solid made of a material with a density of 3200 kg/m³ has a volume of 0.003 m3 and a surface area of 0.07 m². The thermal conductivity of the material is 300 W/m K, and its specific heat is 500 J/kg K. Initially, there is a 100°C difference between the solid and its environment, what is the approximate time it will take for this system to have the difference between its temperature and the environment to be one-third of the initial difference? Use h- 60 W/m-K for the environment. Express your answer in minutes.
A vertical cylinder contains v moles of an ideal gas and is closed off by a piston of mass and area A. The acceleration due to gravity is g. The molar specific heat cy (at constant volume) of the gas is a constant independent of temperature. The heat capacities of the piston und cylinder are negligibly small and any fric- tional forees between the piston and the cylinder walls can be neglected. The whole system is thermaly insulated. Initially, the piston is clamped in position so that the gas has a volume Ve and a tomperature Tn. The pıston is now released and, after some nscillations, comes to rest in a final equilibrium situation corresponding to a larger volumc of the gas. (@) Does the temperature of the gas increase, decrease, or remain the same? (b) Does the entropy of the gas increase, decrease, or remain the same? (c) Calculate the final temperature of the gas in terms of Te, lo, unl the other parameters mentioned in the statement of the prublem.
A food product with 85% moisture content is being frozen. Estimate the specific heat of the product at -10°C when 80% of the water is in a frozen state. The specific heat of dry product solid is 2 kJ/(kg °C). Assume specific heat of water at -10°C is similar to specific heat of water at 0°C. And the heat of the types of ice follow the function of Cp ice = 0.0062 Tfrozen + 2.0649. Cp frozen product = ... kJ/kg °C.
31. The rate of heat conduction out of a window on a winter day is rapid enough to chill the air next to it. To see just how rapidly the windows transfer heat by conduction, calculate the rate of conduction in watts through a 3.00-m? window that is 0.635 cm thick (1/4 in) if the temperatures of the inner and outer surfaces are 5.00°C and –10.0°C, respectively. This rapid rate will not be maintained-the inner surface will cool, and even result in frost formation.

Physical Applications of First-Order DE According to Newton’s law of cooling, the rate at which the temperature of a body changes is proportional to the difference between the instantaneous temperature of the body and the temperature of the surrounding medium. A body cools in air of constant temperature 20 0C according to this law. Ten minutes after the body began to cool, its temperature was observed to be 75 0C, and 10 minutes later its temperature was 50 0 What was its temperature when it began to cool?
