2.38 The addition of aluminum fins has been suggested to increase the rate of heat dissipation from one side of an electronic device 1 m wide and 1 m tall. The fins are to be rectangular in cross section, 2.5 cm long and 0.25 cm thick, as shown in the figure. There are to be 100 fins per meter. The convection heat transfer coefficient, both for the wall and the fins, is estimated to be K. With this information determine the percent increase in the rate of heat transfer of the finned wall compared to the bare wall.

An experiment is undertaken to determine the thermal conductivity of an unknown material. The material is 5 cm thick and has a diameter of 15 cm. It is placed on a hot plate of equal diameter where the surfaces temperature is maintain at 60oC. The outer surface temperature is 24oC, and the power used by the hot plate is 45 W. Determine the thermal conductivity of material.
A cast iron pipe (k = 80 W/m - oC) whose inner and outer diameters are 5 cm and 5.5 cm respectively is coverd with a 3 cm thick glass wool insulation (k = 0.05 W/m - oC) The temperature at the inner surface of the pipe is 320 oC and the interface temperature between the pipe and insulation is 300 oC. Determine the surface temperature of the insulation.
A 2 m X 1.5 m section of wall of an industrial furnace burning gas is not insulated, and the temperature at the outer surface of this section is measured to be 80oC. The temperature of the furnace room is 30oC, and the combined convection and radiation heat transfer coefficient at the surface of the outer furnace is 10 w/oC. It is proposed to insulate this section of the furnace wall with glass wool insulation (K=0.038 W/moC) in order to reduce the heat loss by 90 percent. Assuming the outer surface temperature of the section remains at about 80oC, determine i) the thickness of the insulation that is needed and ii) the outer surface temperature of the insulation after installation.
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…
Two identical aluminum plates with thickness of 30 cm are pressed against each other at an average pressure of 1 atm. The interface, sandwiched between the two plates, is filled with glycerin. On the left outer surface, it is subjected to a uniform heat flux of 7800 W/m2 at a constant temperature of 50°C. On the right outer surface, the temperature is maintained constant at 30°C. Determine the thermal contact conductance of the glycerin at the interface, if the thermal conductivity of the aluminum plates is 237 W/m∙K.

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.
