The heat loss from a boiler is to be held at a maximum of 900 Btu/h ft² of wall area. What thickness of asbestos (k = 0.10 Btu/h ft °F) is required if the inner and outer surfaces of the insulation are to be 1600 and 500°F, respectively?
Added by Dana S.
Step 1
10 Btu/h ft °F - Inner surface temperature (\( T_i \)) = 1600 °F - Outer surface temperature (\( T_o \)) = 500 °F - Required: Thickness of asbestos insulation (\( L \)) Show more…

A pipe with an outside diameter of 65 mm is insulated with a 50 mm layer of asbestos (k = 0.395 Btu-in/hr-ft^2-°F), followed by a layer of cork 40 mm thick (k = 0.30 Btu-in/hr-ft^2-°F). If the temperature of the outer surface of the cork is 90°F, calculate the heat lost per 100 ft of insulated pipe.

A rectangular furnace with inside dimensions 0f 1.0 X 1.0 X 2.0 m has a wall thickness 0f 0.20 m. The k of the walls is 0.95 W/m.K. The inside of the furnace held at 800 K and the outside at 350 K. Calculate the total heat loss from the furnace.
The hot combustion gases of a furnace are separated from the ambient air and its surroundings, which are at 25°C, by a brick wall 0.15 m thick. The brick has a thermal conductivity of 1.2 W/m-K and a surface emissivity of 0.80. Under steady-state conditions, the outer surface temperature of 100°C is measured. Free convection heat transfer to the air adjoining this surface is characterized by a convection coefficient of 20 W/m^2-K. What is the inner temperature?
