Calculate the thermal conductivity of th...

Calculate the thermal conductivity of the composite rod. The two rods A and B are made of two different materials of thermal conductivities `K_1 and K_2` and are welded together.

Text Solution

Verified by Experts

The correct Answer is:
`20 "KW"^(-1)`
`AC and BC` in series. This is in parallel with `AB. R = 60 xx 30//90 = 20 "KW"^(-1)`
