Discuss the below:
Q: Compare the rate of heat flow from the bottom to the top in the aluminum structure shown in the sketch with the rate of heat flow through a solid slab. The top is at -10°C, the bottom at 0°C. The holes are filled with insulation which does not conduct heat appreciably.
GIVEN
The aluminum structure shown in the sketch below
Temperature of the top (TT) = - 10°C
Temperature of the bottom (TB) = 0°C
The holes are filled with insulation which does not conduct heat appreciably
ASSUMPTIONS
The structure is in steady state
Heat transfer through the insulation is negligible
The thermal conductivity of the aluminum is uniform
The edges of the structure are insulated
Two dimensional conduction through thestructure
