Answer:
-Differential equation: d²T/dx² = 0
-The boundary conditions are;
1) Heat flux at bottom;
-KAdT(0)/dx = ηq_e
2) Heat flux at top surface;
-KdT(L)/dx = h(T(L) - T(water))
Explanation:
To solve this question, let's work with the following assumptions that we are given;
- Heat transfer is steady and one dimensional
- Thermal conductivity is constant.
- No heat generation exists in the medium
- The top surface which is at x = L will be subjected to convection while the bottom surface which is at x = 0 will be subjected to uniform heat flux.
Will all those assumptions given, the differential equation can be expressed as; d²T/dx² = 0
Now the boundary conditions are;
1) Heat flux at bottom;
q(at x = 0) is;
-KAdT(0)/dx = ηq_e
2) Heat flux at top surface;
q(at x = L):
-KdT(L)/dx = h(T(L) - T(water))

So that they were less likely to form an uprising and overthrow the slave holders land.
Answer:
(B) heated air in an uninsulated, unvented attic.
Explanation:
-Ice dams are formed by an interaction between snow cover, outside temperatures, and heat lost through the roof – more specifically, from heat loss through the poorly insulated ceiling of the house into the attic area and under the roof.
-Hot, humid air trapped in attics can also cause moisture to accumulate, resulting in mold or mildew.
