The flames in an industrial furnace burn at 800°C on average and the convection coefficientbetween the hot gas and the inside wall of the furnace is ℎ1 = 30 W m2–K⁄ . The wall of thefurnace is made of steel (?? = 20 W m–K⁄ ) and is ? = 10 cm thick. To ensure nobody willburn themself on the exterior surface of the furnace, the steel is to be covered by aninsulating material with a low thermal conductivity (?? = 0.05 W m–K⁄ ). The airsurrounding the furnace is at 27°C and free convection on the exterior wall of the furnaceis expected to produce a convection coefficient of ℎ = 5 W/m2–K. Any radiation effects areexpected to be negligible in this analysis.a) If safety standards require that the outer surface of the furnace not exceed 65°C, howthick should the insulation layer be? This problem is most straightforward if youleverage the concept of thermal resistance.b) Using your result from part (a), calculate the overall heat transfer coefficient (?)from the furnace gas to the ambient…

In a new residential project, you strongly believe that double-paned windows are ‘better’ than single-paned windows. Compare the rate of heat loss between single and double-paned windows(1.5 m x 1 m) if the thickness of each pane is (th = 0.4 cm) and (k = 0.9 W/m.K). The indoor and outdoor temperatures are 18 °C and 2 °C, respectively. Thickness of the air gap between the double-paned windows is (th = 1 cm), and (k = 0.022 W/m.K). Image credit: Windowwhirl.

The insulation is 40 mm thick and covered with a thin layer of metal. The tank contains water that is kept warm by an electric heater in such a way as to maintain the inner surface of the tank at a temperature of 55C.

Question 1: A glass window of width W = 1 m and height H = 2 m is 5 mm thick and has a thermal conductivity of kg =1.4 W/m.K. If the inner and outer surface temperatures of the glass are 15 oC and -20 oC, respectively, on a cold winter day, what is the rate of heat loss through the glass? To reduce heat loss through windows, it is customary to use a double pane construction in which adjoining panes are separated by an air space. If the spacing is 10 mm and the glass surfaces in contact with the air have temperatures of 20 oC and -15 oC, what is the rate of heat loss from a 1 m x 2 m window? The thermal conductivity of air is ka = 0.024 W/m.K.
Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. So it is no surprise that such clothing has largely replaced thick and heavy old-fashioned coats. Consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 W/m·K) with 1.5-mm-thick air space (k = 0.026 W/m·K) between the layers. Assuming the inner surface temperature of the jacket to be 28°C and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0°C and the heat transfer coefficient at the outer surface is 25 W/m2·K. What would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? What should be the thickness of a wool fabric (k = 0.035 W/m·K) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a…
