A rod of varying cross-section carries heat in steady state. Two sections of the same thickness have areas in the ratio 3:1. The temperature difference across the wider section is 10 K. Find the temperature difference in kelvin across the narrower section.
Answer:
30
Solution:
The heat current is the same, so . The narrower section has a 3 times larger difference, K.
