CONDUCTION HEAT TRANSFER
Heat Transfer
Example:
A thick-walled nuclear coolant pipe (ks = 12.5 Btu/hr-ft-°F) with 10 in. inside diameter
(ID) and 12 in. outside diameter (OD) is covered with a 3 in. layer of asbestos insulation
(ka = 0.14 Btu/hr-ft-oF) as shown in Figure 5. If the inside wall temperature of the pipe
is maintained at 550°F, calculate the heat loss per foot of length. The outside temperature
is 100°F.
