Three identical rods have been joined at a junction to make it a Y shape structure .If two free ends are maintained at `60"^(@)C` and the thired end is at `0"^(@)C` then what is the juction temperature `theta`?

Text Solution

Verified by Experts

Rods are in steady state
So, `H=H_1+H_2`
`implies(KA(theta-0))/(L)=(KA(60-0))/(L)+kA((60-theta))/(L)`
`impliestheta=60-theta+60-0`
`implies` 30=120
`implies0=40"^(@)C`
