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.

A long stainless-steel (AISI 316) steam pipe, with an inside diameter of 6.00 cm and an outside diameter of 8.00 cm, is covered with a layer of asbestos insulation (k = 0.150 W/m-K) 1.00 cm thick, which in turn is covered with foam insulation (k = 0.044 W/m-K) 6.00 cm thick. The inside surface temperature of the stainless-steel steam pipe is measured to be 250.0°C, while the outside surface of the foam is exposed to convection, T_inf = 25.0°C, h_inf = 15.0 W/m^2-K. • Draw and label a sketch of this system.

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…

The outer surface of the tank is black (emissivity « = 1), and heat transfer between the outer surface of the tank and the surroundings is by natural convection and radiation.
