Concept explainers
Rank the walls according to the heat flow through the walls from greatest to smallest.
Answer to Problem 68P
The rank of walls according to the heat flow through the walls from greatest to smallest is
Explanation of Solution
Write an expression for the heat flow.
Here,
The temperature difference is same since the heat flows till the equilibrium.
Conclusion:
For wall (a), substitute
For wall (b), substitute
For wall (c), substitute
For wall (d), substitute
For wall (e), substitute
Thus, the rank of walls according to the heat flow through the walls from greatest to smallest is
