During the winter, the inside of an average house is maintained at 20 °C, while the outside temperature is 0 °C. Assuming that the only mechanism of heat transfer is conduction, the walls are 10 cm thick and the heatconductivity of the walls is 0.5 W/(Km). a) Calculate the heat flux from the room to the surroundings in W/m2. b) To reduce the heat loss through the walls, the material should be changed to an insulator material. Thenew overall conductivity will be 0.1 W/(Km); the thickness of the walls is maintained. Calculate the reductionof the heat flux through the walls compared to the initial case.
Suppose 170 W of heat flows by conduction from the blood capillaries beneath the skin to the body's surface area of 1.5 m2.
If the temperature difference is 0.50 C, estimate the average distance of capillaries below the skin surface.
How much heat transfer (in kilocalories) is required to thaw a 0.450-kg package of frozen vegetables originally at 0C if their heat of fusion is the same as that of water?
