Transmission Of Heat Question 329
Question: All the rods have same conductance K and same area of cross section A. If ends A and Care maintained at temperature 2Ty and T respectively then which of the following is/are correct:
Options:
A) Rate of heat flow through ABC, AOC and ADC is same
B) Rate of heat flow through BO and OD is not same
C) Total Rate of heat flow from A to C is $ \frac{P _{o}}{P _{He}}=\frac{1}{8} $
D) Temperature at junctions B, O and D are same
Show Answer
Answer:
Correct Answer: D
Solution:
[d] By symmetry $ I _{AB}=I _{BC} $ and $ I _{AD}=I _{DC} $
$ \
Therefore $ No current in BO and OD $ T _{B}=T _{O}=T _{D} $
